Jessica Alba

After playing a genetically enhanced guy-magnet on the sci-fi series Dark Angel, Jessica Alba took her toned body to the big screen in Honey, Sin City and The Fantastic Four. Though few of her films have been huge box office hits, her star continues to rise, thanks in part to her dedicated male fan base and stunning looks.

While her flawless beauty landed her contracts with L'Oréal and Revlon, Alba refuses to use it for nude scenes and once sued Playboy for publishing a photo of her on its cover without permission. In 2008, Alba, who was previously engaged to Dark Angel costar Michael Weatherly, started a family with husband Cash Warren, with whom she has two daughters Honor and Haven.
