Sara Foster

Statuesque Malibu blonde Sara Foster, by age 18, was a top model featured in campaigns for Guess, Ralph Lauren, and Tommy Hilfiger before beginning her acting career. She bounced from a brief stint hosting the "Entertainment Tonight"-spinoff, "ET on MTV," to being cast as the femme fatale, opposite Owen Wilson, in the 2004 remake of "The Big Bounce."

The film disappointed at the box office, but Foster charmed audiences with her wry, seductive performance, and soon found herself playing "Herself" on an episode of HBO's Hollywood-skewering comedy series, "Entourage"; she literally charmed the pants off the show's Vince Chase (played by Adrian Grenier) during a memorably sexy backstage rendezvous at a taping of "Jimmy Kimmel Live." Foster added a karate kick to her sultry onscreen persona in the action comedy "D.E.B.S." (2005) as Amy Bradshaw, one-fourth of an elite team of schoolgirl secret agents; she jeopardizes her squad's high-stakes mission by falling for their beguiling arch-nemesis, Lucy Diamond (played by Jordana Brewster).

The movie drew raves primarily for its straightforward lesbian love story, and certainly attracted fans for Foster, who landed on magazine covers and Most Beautiful lists, and soon moved to the CW Network's teen soap "90210"; she played over-the-top villainess Jen Clark, actress sister of resident vixen Naomi (portrayed by AnnaLynne McCord). In fact, Foster, like her character, is well-connected in Hollywood: her father is Grammy-winning songwriter and producer David Foster; she married tennis pro Tommy Haas; and she famously introduced Ashton Kutcher to his future wife, Demi Moore.
