Age: 28
Occupation: Actress
Besides possessing classic film starlet looks, unlike a lot of these other pretty faces populating Hollywood, Olivia Wilde can actually act. Since her breakout role in The O.C., Olivia has steadily built the foundation for a career that will last when (or if) the looks fade. It also helps that she changed her surname from Cockburn to Wilde. Just sayin'.

DECADE ACHIEVEMENT: Playing Quorra, the sexy "isomorphic algorithm," in Disney's big-budget popcorn flick Tron: Legacy.
