Ashlee Simpson

Ashlee Simpson

Birth Date: October 03, 1984
Birth Place: Waco, Texas

Ashlee Simpson was building a credible singing career when she lip-synched on Saturday Night Live. Although she was ridiculed in the aftermath of the headline-grabbing snafu, Simpson kept going, cementing her own spot in pop culture outside of being Jessica's little sister.

With her newly-colored brunette locks and punk sound, Simpson documented the making of her first album, Autobiography, on MTV's The Ashlee Simpson Show. Simpson's debut went triple-platinum, followed by an equally successful follow-up, I Am Me, which featured Simpson and her new nose.

In 2008, the youngest Simpson got engaged to Fall Out Boy bassist Pete Wentz and released her third album, Bittersweet World, among pregnancy reports.

Carrie Underwood

Carrie Underwood

Birth Date: March 10, 1983
Birth Place: Muskogee, Oklahoma

Before auditioning for American Idol in 2004, Carrie Underwood had never been on an airplane. She was just a small-town Checotah, Okla. gal who attended Wednesday night prayer meetings and competed in local talent shows.

But with her sweet demeanor, megawatt smile and powerful country vocals, Underwood beat rocker Bo Bice in the finale of Idol's fourth season, and transformed into a full-blown, Grammy-winning superstar in two short years. Her debut album Some Hearts even helped her beat country music's reigning queen Faith Hill in the awards race, with Hill controversially screaming 'What?' at a backstage camera.

At 24, Underwood, who has been linked to Dallas Cowboys' Tony Romo and Gossip Girl's Chace Crawford, solidified her place in country with her first No. 1 album, Carnival Ride, right after winning two of Nashville's biggest honors (for the second time) at the 2007 CMA Awards.

Keith Urban

Keith Urban

Birth Date: October 26, 1967
Birth Place: Whangarei, New Zealand

Kiwi cowboy Keith Urban has plenty to sing about, from his battle with drugs and alcohol to his love and marriage with fellow Aussie and Oscar-winning actress Nicole Kidman.

Just four months after their wedding, the country music superstar checked into rehab, calling his life "unmanageable." He missed the Country Music Awards, where he won his third consecutive statuette as Male Vocalist of the Year. But in January 2007, Urban emerged from rehab renewed, crediting Kidman's love and devotion to making him a new man. In 2008, Urban will also become a daddy, as his movie star wife announces her first pregnancy at age 40.

Jennifer Lopez

Jennifer Lopez

Birth Date: July 24, 1969
Birth Place: Bronx, N.Y.

Jennifer Lopez has always laughed off the rumors that her derriere is insured for $1 billion, but there's no doubt about her assets. Her first starring role in 1997's Selena showcased her talents as an actress and singer – but it was those tight costumes and the curves they revealed that made her a sex symbol.

That breakthrough performance launched a multifaceted career that includes albums, movies, clothes and perfume. But it was Lopez's love life with music mogul Sean ''Diddy'' Combs and actor Ben Affleck that catapulted her into tabloid headlines. After the rocky, high-profile engagement that was "Bennifer" ended, Lopez quietly married Latin singer Marc Anthony. In February 2008, after months of baby bump sightings, Lopez and Anthony welcome twins, a boy named Max and a girl named Emme.

Justin Timberlake

Justin Timberlake

Birth Date: January 31, 1981
Birth Place: Memphis, Tenn.

Justin Timberlake has been known as a Mouseketeer, frontman of boy band 'N Sync, and boyfriend of pop princess Britney Spears. But he shelved this good-boy persona when he embarked on a successful solo career in 2002, with songs promising to "rock your body" and "bring sexy back."

Post-Britney, Timberlake was linked to several older women, such as actress Alyssa Milano and Janet Jackson, whose nipple he accidentally revealed during the infamous 2004 Super Bowl halftime show. In 2003, Timberlake met Cameron Diaz, nine years his senior, whom he dated for nearly four years before moving on with actress Jessica Biel.

Jennifer Hudson

Jennifer Hudson

Birth Date: September 12, 1981
Birth Place: Chicago, Ill.

Jennifer Hudson's awe-inspiring turn as Effie White in Dreamgirls made the world forget that Simon Cowell told her she resembled "something you should wrap a turkey in." Not only did the American Idol reject upstage an Oscar winner and pop superstar, she also earned an Oscar for Best Supporting Actress.

A performer since childhood in her family's South Side of Chicago Baptist church, Hudson did a stint aboard the Disney Wonder cruise before competing on the third season of American Idol. After her early elimination, Hudson soldiered on, eventually beating 781 hopefuls for her star-making role in Dreamgirls. Hudson has since signed a recording contract with Clive Davis, taken her curves to the cover of Vogue, and proven she was more than a one act wonder with a role in the highly anticipated Sex and the City movie.

John Mayer

John Mayer

Birth Date: October 16, 1977
Birth Place: Bridgeport, Conn.

John Mayer's got five Grammy Awards, been dubbed a "guitar hero" by Rolling Stone, and released three platinum-selling albums, but it was a relationship with a little-known starlet by the name of Jessica Simpson that made him paparazzi material.

With his lanky 6'3" frame and puppy-dog eyes, the Connecticut-bred musician once told Entertainment Weekly, "I really don't want to be a hunk." But with hits like "Your Body is a Wonderland" and hook-ups with Jennifer Love Hewitt and Cameron Diaz, Mayer's become a reluctant hottie. To his credit, Mayer has transitioned from pop poster boy to up-and-coming blues legend, and in 2007, Time magazine named him one of its 100 Most Influential People in the World, saying "This white boy has something to say about the blues."

Kate Moss

Kate Moss

Birth Date: January 16, 1974
Birth Place: Surrey, England

Kate Moss' waif-like image has propelled her long and lucrative career as a supermodel and fashion icon. Though rail-thin and short by early '90s standards (think Cindy Crawford), the London-born Moss vaulted to fame in Calvin Klein campaigns. Her own style choices – denim cutoffs, skinny jeans, waist-cinching belts – launched trends, too.

In 2005, it seemed Moss' career was over when the Daily Mirror published photos of Moss allegedly snorting cocaine. The supermodel temporarily lost major clients. But her career held up as she launched her own fashion line for Topshop and was named one of Time magazine's Most Influential People for having "the face that has never gone out of style."

Hugh Jackman

Hugh Jackman

Birth Date: October 12, 1968
Birth Place: Sydney, Australia

A charismatic song-and-dance man with serious acting chops, Tony winner Hugh Jackman made a strong impression as the edgy Wolverine in the X-Men trilogy.

For the hunk from Down Under, important roles followed in Swordfish (with Halle Berry), the monster flick Van Helsing (opposite Kate Beckinsale), and Woody Allen's Scoop (with Scarlett Johansson). But, it was his star turn in the Broadway musical The Boy From Oz that surprised fans and critics, earning him a Tony in 2004. The following year, he won an Emmy for his work hosting the Tonys broadcast.

Kristen Bell

Kristen Bell

Birth Date: July 18, 1980
Birth Place: Detroit, Mich.

The teen noir series Veronica Mars wilted in the ratings, but its star Kristen Bell left the cancelled show with a fanatic cult following and a heroic career rebound.

The Detroit native dropped out of New York University's prestigious Tisch School to pursue stage roles with Laura Linney and Liam Neeson on Broadway. She soon moved to L.A. and within weeks landed guest appearances on The Shield and HBO's Deadwood before her star-making turn as the witty and spunky teen detective on Mars. Though the series ended after three seasons, Bell didn't miss a beat: she moved onto NBC's Heroes and the comedy Forgetting Sarah Marshall, which is produced by The 40-Year-Old Virgin's Judd Apatow slated for 2008.

Keanu Reeves

Keanu Reeves

Birth Date: September 02, 1964
Birth Place: Beirut, Lebanon

Whoaaa – that's Keanu Reeves' trademark phrase, first uttered as dimwitted stoner Ted Logan in Bill & Ted's Excellent Adventure. To battle being typecast as brainless, Reeves tackled Shakespeare onstage as Hamlet and onscreen in Much Ado About Nothing, opposite Denzel Washington. But it was his action hero roles in Speed and the Matrix trilogy that put the excellence in his career.

His personal life has been less charmed. Girlfriend Jennifer Syme gave birth to a stillborn daughter before her death in a 2001 car accident; his sister Kim is fighting leukemia. When he's not acting, Reeves rides motorcycles, plays bass in his rock band Dogstar, and leads a largely reclusive life.

Naomi Watts

Naomi Watts

Birth Date: September 28, 1968
Birth Place: Shoreham, England

After her electrifying portrayal of a troubled lesbian in David Lynch's Mulholland Drive (2001), Naomi Watts appeared to be an "overnight" success. In reality, it took nearly 20 years of auditions and bit parts before she "made it."

While struggling for her own big break, Watts watched her best friend, Nicole Kidman, become one of Hollywood's most in-demand actresses, without a hint of jealousy. But her fortunes changed when she starred in the horror remake, The Ring. She also showed her range with an Oscar-nominated performance in 21 Grams and the Fay Wray role in Peter Jackson's King Kong.

In 2002, Watts began dating Heath Ledger intermittently for two years despite a ten-year age difference, before moving on with actor Liev Schreiber. In July 2007, Watts and Schreiber welcomed their first child, Alexander Pete.

Jennifer Aniston

Jennifer Aniston

Birth Date: February 11, 1969
Birth Place: Sherman Oaks, Calif.

Jennifer Aniston catapulted into stardom as spoiled-but-lovable Rachel Green on the hit TV series Friends. "The Rachel," her layered haircut during the show's second season, sparked a nationwide trend and transformed Aniston into a style icon.

In 2000, she married heartthrob Brad Pitt, but filed for divorce four and a half years later. When reports emerged of Pitt's romance with Mr. & Mrs. Smith costar Angelina Jolie, Aniston earned admiration from fans for her poise and resilience. But, she quickly rebounded with The Break-Up costar Vince Vaughn. Although the pair has since split up, Friends costar Courteney Cox Arquette still says of her real-life best friend, "It's impossible not to like this girl."

Johnny Depp

Johnny Depp

Birth Date: June 09, 1963
Birth Place: Owensboro, Ky.

Johnny Depp is known for playing eccentric characters – from his work with horror-meister director Tim Burton (Edward Scissorhands, Sweeney Todd) to Disney's edgy Captain Jack Sparrow in the Pirates of the Caribbean movies.

With his shock of black hair and distinctive high cheekbones, the Kentucky-born Depp has progressed from '80s teen heartthrob in the Fox TV series 21 Jump Street, to PEOPLE's Sexiest Man Alive in 2003. But he hasn't relied on his stunningly sexy good looks, having notoriously spurned conventional leading-man roles in Titanic and Speed. Rarely seen in Hollywood, Depp, who previously dated Winona Ryder and Kate Moss, lives quietly in the south of France with actress Vanessa Paradis and their two children.

Kate Winslet

Kate Winslet

Birth Date: October 05, 1975
Birth Place: Reading, England

As a testament to her talent, Kate Winslet is a record holder: She's the youngest actress to earn five Academy Award nominations, receiving her first nod for Jane Austen's Sense and Sensibility (1995) and her latest for Little Children (2007).

Winslet's heart-wrenching performance in 1997's megahit Titanic made her a household name, of course, but her voluptuous figure has continued to steal headlines: The mother of two openly detests ultra-thin stars, sued a magazine for claiming she saw a diet specialist, and spoke out against a 2003 GQ cover, where she had been digitally slimmed. But at the end of the day, it has always been about the acting: Winslet can next be seen reteaming with Titanic costar Leonardo DiCaprio for the upcoming Revolutionary Road, directed by her Oscar-winning husband Sam Mendes.

Nick Lachey

Nick Lachey

Birth Date: November 09, 1973
Birth Place: Harlan, Ky.

When Nick Lachey married a relatively unknown pop singer named Jessica Simpson, he had already sold seven million albums as a member of 98 Degrees. But it was MTV's reality show Newlyweds that seared him and then-wife into pop-culture consciousness.

On Newlyweds, Lachey played the endearingly patient husband to Simpson's blundering blonde. Opening their marriage to TV viewers and tabloids alike, Lachey and Simpson were persistently nagged by breakup reports, and the day before Thanksgiving 2005, the couple announced their separation, eventually ending their three-year union.

Though Lachey refrained from public mudslinging, he didn't shy away from putting his feelings to song in his album, What's Left of Me. The avid sports fan and minor league baseball team owner has since moved on – and in – with the stunning Vanessa Minnillo.

Penélope Cruz

Penélope Cruz

Birth Date: April 28, 1974
Birth Place: Madrid, Spain

Although she came to Hollywood with 20 films and a Spanish Academy Award under her belt, screen siren Penélope Cruz became best known in America as the off-screen girlfriend of costars Tom Cruise and Matthew McConaughey.

After appearing in a string of mediocre films from All the Pretty Horses to Sahara, Cruz returned to her roots and collaborated with Oscar-winning writer-director Pedro Almodóvar on the Spanish-language dramedy Volver. Her gut-wrenching portrayal of a mother dealing with her teenage daughter's crisis and the death of her own mother made Cruz the first Spanish Best Actress nominee in Oscar history.

The brunette bombshell, who landed contracts with designer Ralph Lauren and cosmetics brand L'Oreal, once called herself a "serial monogamous," but was recently linked to Javier Bardem, Orlando Bloom and Josh Hartnett.

Gwen Stefani

Gwen Stefani

Birth Date: October 03, 1969
Birth Place: Anaheim, Calif.

It was a breakup that led to singer Gwen Stefani's breakthrough. After her seven-year relationship with No Doubt bandmate Tony Kanal ended, Stefani channeled the loss into No Doubt's 1995 smash album, Tragic Kingdom. Fueled in part by Stefani's trend-setting style, No Doubt went on to become a major influence on the '90's music scene.

In 2004, Stefani went solo and made waves with over-the-top fashions and an ever-present entourage of harajuku girls. Additionally, the multi-tasking performer appeared in The Aviator and created the retail line L.A.M.B. In 2002, the pop icon married former Bush singer Gavin Rossdale, with whom she is expecting her second child.

Liv Tyler

Liv Tyler

Birth Date: July 01, 1977
Birth Place: New York, N.Y.

A 1988 Aerosmith concert changed Liv Rundgren's world forever: It was there she learned that the band's Steven Tyler (those lips!) was her biological father.

In the 1990s, Liv Tyler put her ga-ga gorgeous looks – and new surname – to good use, landing on the cover of Seventeen at age 15. But her breakout role can be credited to her father, Steven. In the 1994 Aerosmith music video, "Crazy," she played a schoolgirl who ditches class to hang out at a strip club with Alicia Silverstone. The video turned her into a rock sex symbol and led to roles in such movies as the tender coming-of-age film Stealing Beauty, blockbusters like Armageddon and the record-breaking Lord of the Rings trilogy. Tyler, who can be seen next in The Incredible Hulk, is married to British musician Royston Langdon. They had a son, Milo, in 2004.

Nicole Richie

Nicole Richie

Birth Date: September 21, 1981
Birth Place: Berkeley, Calif.

The secret of Nicole Richie's childhood? Her parents' "way of making me happy was to say yes to everything I wanted." Of course. Adopted by singer Lionel Richie, she grew up in privileged L.A. society, where her playmates included hotel heiress Paris Hilton. In 2003, the pair starred in the reality show, The Simple Life. After arrests and problems with drugs, Richie found herself in rehab as the first season aired.

Often accused of being too thin, Richie became a style icon, with endless coverage of her shrinking frame and on-and-off relationships. Richie continued working with Hilton although they famously fell out, but reconciled in 2006 before starring in their show's fifth season. She's dating Hilary Duff's ex, rocker Joel Madden, and she gave birth to their first child, Harlow Winter Kate Madden in January 2008.

George Clooney

George Clooney

Birth Date: May 06, 1961
Birth Place: Lexington, Ky.

George Clooney earned a living through the '80s with bit parts on The Facts of Life and Roseanne, but at 33, he raised heart rates and his celebrity status as Dr. Doug Ross on the NBC juggernaut ER.

Clooney became a household name and bonafide sex symbol (twice dubbed by PEOPLE the Sexiest Man Alive). When he made the jump to the big screen, Clooney alternated between big-budget studio films (the Ocean's Eleven franchise) and smaller, more politically minded fare. He earned Oscar nods for directing and cowriting Good Night, and Good Luck, and that same year, Clooney became an Oscar winner for his supporting role in Syriana.

Pamela Anderson

Pamela Anderson

Birth Date: July 01, 1967
Birth Place: Ladysmith, British Columbia, Canada

Male fans gave hearty applause to a fresh-faced Pamela Anderson when she and her Labatt beer T-shirt were splashed on the JumboTron at a football game in British Columbia. The random moment kickstarted her sexy career as one of Playboy's most successful playmates.

After playing Tim Allen's Tool Time girl in Home Improvement, she garnered worldwide fame with a slow-motion running sequence in a red swimsuit on Baywatch. She went on to marry rocker Tommy Lee, which resulted in a leaked sex tape, two children, Hepatitis C, and a divorce. Anderson moved on, though, with a brief marriage to Kid Rock in 2006 before trying her hand at marriage again in October 2007 with Rick Saloman – best known for performing in and distributing Paris Hilton's sex tape. By March, she ended another marriage.

Rachel McAdams

Rachel McAdams

Birth Date: October 07, 1976
Birth Place: London, Ontario, Canada

After starring in the body-swap comedy The Hot Chick, Rachel McAdams won praise for her performance as Lindsay Lohan's catty archenemy in 2004's Mean Girls. But it was the widely popular love story, The Notebook, where she fell in love with costar Ryan Gosling, that got her dubbed as the next Julia Roberts.

But McAdams remains grounded, ditching Hollywood for her Canadian hometown. She even bowed out of a coveted Vanity Fair cover shoot with Keira Knightley and Scarlett Johansson when she learned she was to pose nude. Since then, she's appeared in The Family Stone with Sarah Jessica Parker and Wedding Crashers alongside Owen Wilson and Vince Vaughn.

Oprah Winfrey

Oprah Winfrey

Birth Date: January 29, 1954
Birth Place: Kosciusko, Miss.

When young Oprah Winfrey dated movie critic Roger Ebert, he persuaded her to take her successful Chicago talk show into syndication. By 1986, The Oprah Winfrey Show had become the highest-rated talk show in TV history.

Now worth more than a billion dollars, Winfrey has succeeded on many fronts – as an Oscar-nominated actress (The Color Purple), activist, magazine editor, producer, book club sponsor and radio host.

She has raised and personally donated millions of dollars to victims of poverty and disease and openly speaks about her own experience with sexual abuse as a child, the baby she had at 14 who did not survive, and of her drug use as a young adult. But, according to Winfrey, none of her achievements make her more proud than the two schools she opened for South Africa's neediest girls.

Mary-Kate Olsen

Mary-Kate Olsen

Birth Date: June 13, 1986
Birth Place: Sherman Oaks, Calif.

Mary-Kate and Ashley Olsen are known for their signature style, but the twins were first famous as Michelle Tanner on Full House. Before turning 10, they had already earned millions, and at 18, took charge of their billion-dollar brand, Dualstar.

In 2004, Mary-Kate battled anorexia, later ending her studies at New York University. Soon after, the New York Times dubbed her a fashion star, and she modeled couture with her sister Ashley for Badgley Mischka before launching their fashion line, The Row. Today, Mary-Kate travels between L.A. and New York to pursue her acting career, which includes a recurring role on the Showtime series Weeds.

Orlando Bloom

Orlando Bloom

Birth Date: January 13, 1977
Birth Place: Canterbury, England

The Sexiest Man Alive nearly didn't make it. While still a drama-school student in England, Orlando Bloom fell three stories, breaking his back. He could have been paralyzed, but Bloom walked out of the hospital on crutches.

Nice timing. Just before graduation, director Peter Jackson picked him to star as elf warrior Legolas in The Lord of the Rings trilogy, now among the highest grossing films of all time. In 2002, he scored another blockbuster franchise, Pirates of the Caribbean.

In 2006, Bloom's four-year, on-and-off again romance with Kate Bosworth ended, and he has since been linked to Spanish siren Penélope Cruz. Although Bloom is taking a break from making movies, his luck still seems intact. To date, he has also survived a broken nose, ribs, arm, wrist, both legs, a finger and a toe.

Renée Zellweger

Renée Zellweger

Birth Date: April 25, 1969
Birth Place: Katy, Texas

After a star-making turn opposite Tom Cruise in Jerry Maguire, pouty-lipped Renée Zellweger has provided audiences with a series of surprises.

She earned the wrath of England when she (a Yank) was cast as the London working-girl heroine of Bridget Jones's Diary. Though much attention was focused on her weight gain (and drastic, subsequent loss), Zellweger earned her first Oscar nod. A second nomination came for the hit musical Chicago, but she finally won an Oscar for her supporting role opposite Nicole Kidman in 2003's Cold Mountain.

The actress, who has dated Jim Carrey and White Stripes frontman Jack White, quickly married country musician Kenny Chesney in May 2005, but the union was annulled just four months later. She has since picked up the pieces and moved on to roles in Jerry Seinfeld's animated feature Bee Movie and George Clooney's Leatherheads.

Janet Jackson

Janet Jackson

Birth Date: May 16, 1966
Birth Place: Gary, Ind.

Jaws dropped when Janet Jackson appeared on the cover of Rolling Stone with a pair of men's hands covering her breasts in 1993, but she created an even bigger stir at the 2004 Super Bowl halftime show when Justin Timberlake ripped her bustier off, revealing her nipple.

The scandal launched a national debate about indecency, but it couldn't trump her achievements as an entertainer. The youngest of the nine Jackson offspring, Janet cemented her own place in the world of pop and R&B outside of her brother Michael's shadow with albums like Control, Rhythm Nation and The Velvet Rope.

In 2006, after notoriously keeping mum on her nine-year marriage to Rene Elizondo, Jackson changed things up when she went public with her relationship with fellow music veteran Jermaine Dupri.

Evan Rachel Wood

Evan Rachel Wood

Birth Date: September 07, 1987
Birth Place: Raleigh, N.C.

Evan Rachel Wood shot to fame as every parent's rebellious nightmare in the teenage coming-of-age drama, Thirteen, and in real-life rose many eyebrows by falling for shock rocker Marilyn Manson, who is almost twice-her-age.

But her love affair with the dark musician didn't overshadow her acclaimed acting career. By 20, the Raleigh-born actress, who grew up doing theatre, has shared the screen with Oscar winners Nicole Kidman in Practical Magic, Cate Blanchett in The Missing and Gwyneth Paltrow in Running with Scissors. In 2007, Wood belted out Beatles tunes in Across the Universe and starred alongside Michael Douglas in King of California.

Scarlett Johansson

Scarlett Johansson

Birth Date: November 11, 1984
Birth Place: New York, N.Y.

Scarlett Johansson was just 11 years old when a role in indie film Manny & Lo earned her an Independent Spirit Award nomination. At 14 she impressed audiences and critics with a mature turn in Robert Redford's The Horse Whisperer. But her ascension to A-list status really began with a lingering close-up of her shapely, pink panty-clad derriére in the opening scene of the Oscar-winning film Lost in Translation.

Johansson has continued to make career-building film choices with roles in Girl With A Pearl Earring and Woody Allen’s Match Point. Offscreen, the bombshell, who was voted Esquire's Sexiest Woman Alive, has been linked to Jared Leto, Josh Hartnett and most recently Ryan Reynolds.

Shakira

Shakira

Birth Date: February 02, 1977
Birth Place: Barranquilla, Colombia

Her 2005 album could've been called Aural Fixation, because Shakira's unique version of sexy, heartfelt Latin pop has turned her into a mass-market obsession. The hip-shaking singer released her first Spanish-language album as a teenager, and by the late '90s, her albums – and a role on the soap opera El Oasis – had made Shakira a huge star throughout Latin America and Spain.

To conquer America, she headlined MTV's Unplugged, and the recording of her acoustic performance won a Latin Grammy in 2000. Shakira began taking English lessons, and the following year, her English-language debut, Laundry Service, entered the charts at No. 3.

However, Shakira considers her work battling childhood poverty just as important as her music career. The other love in her life, fiancé Antonio de la Rua, is the son of Argentina's controversial former president.

Salma Hayek

Salma Hayek

Birth Date: September 02, 1966
Birth Place: Coatzacoalcos, Mexico

Salma Hayek departed Teresa, the Mexican soap opera that made her famous in her home country, after two years. In the U.S., she paid her dues with bit parts before her break opposite Antonio Banderas in 1995's gun-heavy revenge flick, Desperado.

Hayek has decried the lack of quality roles for Latinas in Hollywood, but instead of fading into obscurity, she created new roles as a producer. She produced and starred in Frida, which earned Hayek an Oscar nomination for Best Actress, and as executive producer, she created the hit ABC series Ugly Betty, which made actress America Ferrera a household name and Emmy winner.

In September 2007, Hayek and her fiancé, businessman François-Henri Pinault, welcomed a baby girl, Valentina Paloma. Prior to Pinault, Hayek dated actor Edward Norton for several years, and was once linked to Josh Lucas.

Sheryl Crow

Sheryl Crow

Birth Date: February 11, 1962
Birth Place: Kennett, Mo.

February 2006 was a rough month for Sheryl Crow. She split with fiancé Tour de France champion Lance Armstrong. Then, soon after her 44th birthday, a lump was found during a routine mammogram. But Crow beat breast cancer without missing a note – even returning to her tour after surgery and radiation treatment.

She broke onto the music scene in 1993 with her folksy rock album, Tuesday Night Music Club, which led to three Grammys and sold more than 7 million copies. Eight years later, she went glam at 40 with a sexier look and new pop-influenced sound that rounded her Grammy collection to nine.

Today, Crow splits her time between her music, her cancer and ecological causes, and her son Wyatt Steven, whom she adopted in May 2007.

Sienna Miller

Sienna Miller

Birth Date: December 28, 1981
Birth Place: New York, N.Y.

Sienna Miller knows her love life overshadowed her acting career, referring, of course, to the headlines generated in 2005 when she left fiancé Jude Law, who confessed to an affair with his children's nanny.

Before "Nannygate," Miller gained a reputation as a stunning scene-stealer from her short, yet memorable roles in the gritty crime film Layer Cake and 2004's Alfie. The latter marked the beginning of her tumultuous, on-and-off again relationship with much-bigger star Jude Law. After finally calling it quits in 2006, Miller emerged from the shadow of their romance with an edgy film role in Factory Girl as Andy Warhol muse Edie Sedgwick. Like Sedgwick, Miller wields considerable fashion influence and parlayed it into her own line, Twenty8Twelve, which she designs with her sister Savannah. The stunning Londoner can next be seen alongside Keira Knightley in The Edge of Love.

Taylor Swift

Taylor Swift

Birth Date: December 13, 1989
Birth Place: Wyomissing, Pa.

Taylor Swift, country music's hottest teen phenom since LeAnn Rimes, has written more than 250 songs, including the 11 tracks from her self-titled debut disc. With such hits as "Tim McGraw" and "Our Song," the 5'11" beauty with serious musical talent, has already sold more than 2.5 million albums.

Although Swift has been eager to stake her claim in country music since age 11, she's taken Goldilocks' "just right" philosophy when it comes to record deals: she backed out on a contract that didn't let her write and sing her own songs – and she was barely 14. After her 2006 debut, the high school senior nabbed a Grammy nomination for Best New Artist and won a CMA Horizon Award, all before her 18th birthday.

Teri Hatcher

Teri Hatcher

Birth Date: December 08, 1964
Birth Place: Sunnyvale, Calif.

When Teri Hatcher won a 2005 Golden Globe for her role as Susan Mayer in the runaway success Desperate Housewives, she thanked ABC for giving her a chance "when I couldn't have been a bigger has-been." That refreshing self-awareness made her a hit (again) with Hollywood.

Hatcher's career began when she accompanied a friend to an audition to lend moral support – and won the part of a singing, dancing mermaid on Love Boat in 1985. But it was her turn as sexy, spirited Lois Lane in Lois & Clark: The New Adventures of Superman that made her a small screen star.

Since returning to the public eye, Hatcher has published a memoir (Burnt Toast) and is frequently photographed with her daughter Emerson, whose father is Hatcher's former husband Jon Tenney.

Tori Spelling

Tori Spelling

Birth Date: May 16, 1973
Birth Place: Los Angeles, Calif.

Through the '90s, Tori Spelling was known as TV's most famous virgin – which is what happens when your father, legendary TV producer Aaron Spelling, casts you in his hit show, Beverly Hills, 90210, and refuses to let you be deflowered on air for seven long years.

Though nepotism made her a star, Spelling's determination and self-deprecating wit endeared her to audiences on 10 seasons of 90210. She launched a prolific made-for-TV movie career, and produced and starred in the VH1 satirical sitcom, So NoTORIous. After her father's death in 2006, she weathered a well-publicized rift with her mother, Candy, but the birth of Spelling's son, Liam Aaron, with second husband Dean McDermott brought the estranged mother and daughter closer together.

In 2007, Spelling starred with McDermott in their Oxygen network reality show, Tori & Dean: Inn Love, which followed the couple as they ran their B&B in Fallbrook, Calif. Of motherhood, Spelling, who is expecting her second child with McDermott in 2008, says it "rocks".

Usher

Usher

Birth Date: October 14, 1978
Birth Place: Dallas, Texas

By age 26, Usher sold more than 25 million albums worldwide, won five Grammy awards, headlined a 64-city tour that earned him more than $20 million, and dated TLC's Rozonda "Chilli" Thomas and supermodel Naomi Campbell.

After appearing on Star Search, the 13-year-old signed with LaFace Records, where he was mentored by Sean ''Diddy'' Combs and Jermaine Dupri. He lit the world of R&B and pop up with his megawatt smile, six-pack abs, smooth vocals and slick dance moves. With such hits as "Burn," "Confessions" and "Yeah!" Usher became the third artist ever to have three singles simultaneously on Billboard's Top 10.

In 2007, he made headlines for his stop-and-go nuptials with former stylist-turned wife Tameka Foster. That November, the newlyweds welcomed their first child together – a boy they named Usher Raymond V.

Vanessa Hudgens

Vanessa Hudgens

Birth Date: December 14, 1988
Birth Place: Salinas, Calif.

As the smart, sugary sweet songbird Gabriella Montez on the Disney Channel megahit High School Musical, Vanessa Hudgens became tweens' favorite girl next door. But her pristine image took on some tarnish in September 2007 when a nude photo of the teen (taken prior to her fame) surfaced on the web.

The notoriety hasn't hurt the California native, who knew she wanted to perform early on and took piano, dance and vocal lessons to get there. At 13, she made her TV debut on an episode of Still Standing before landing the role that would make her a teen idol and introduce her to real-life love, heartthrob Zac Efron. Riding on her HSM fame, Hudgens released her debut album, V, signed on to endorse Neutrogena, reprised her role in the massively successful HSM2, and finally took her relationship with Efron public.

Vince Vaugh

Vince Vaugh

Birth Date: March 28, 1970
Birth Place: Buffalo Grove, Ill.

Every time a twentysomething man yells, "Vegas, baby!" there is one man to thank: Vince Vaughn, the rambunctious sidekick prone to spouting quotable one-liners in Swingers. A year after the film's release, he was starring in Steven Spielberg's Jurassic Park sequel before returning to the comedic style that made him a box-office success.

Vaughn's fast-talking, giddy, manic energy made hits out of Dodgeball, Old School and The Wedding Crashers. It even turned the critically maligned Jennifer Aniston romantic comedy The Break-Up into a commercial hit, eventually spawning a well-publicized off-screen romance as well. But the Aniston-Vaughn pairing was plagued with media scrutiny, and they eventually called it quits in December 2006. Vaughn has since concentrated on film with roles in Sean Penn's adaptation of Into the Wild and the holiday comedy Fred Claus.

Will Smith

Will Smith

Birth Date: September 25, 1968
Birth Place: Philadelphia, Pa.

With his versatility, easy wit, and family-friendly charm, rapper-turned-actor Will Smith has become one of Hollywood's most bankable multitaskers.

As half of the rap duo DJ Jazzy Jeff and the Fresh Prince, Smith found success with such mom-friendly hits as "Parents Just Don't Understand" that appealed to teenagers without using violent, vulgar lyrics. He branched out to TV with The Fresh Prince of Bel-Air, a successful sitcom that aired for several seasons and is still widely syndicated.

Smith, who has two children with wife Jada Pinkett Smith and a son from a previous marriage, soon began starring in big-screen blockbusters such as Bad Boys, Independence Day and Men in Black and soon found success in more serious fare. His portrayal of the ex-heavyweight champ in Ali, earned Smith his first Oscar nomination for Best Actor, with his second Best Actor nomination coming in 2007 for The Pursuit of Happyness.

Before taking home the Oscar, her career was a balance of big-budget movies (Die Another Day, the X-Men trilogy) and critically acclaimed dramas (Spike Lee's Jungle Fever and played the title role in Introducing Dorothy Dandridge). Despite her professional success and stunning beauty, the actress failed to find lasting love. She divorced Atlanta Braves baseball player David Justice and second husband, singer Eric Benét – both of whom cheated on her.
