20. Keira Knightley
It’s easy to dismiss her as just a pretty face—unless you see her act. The talented Brit can handle the highbrow (she received a Best Actress nod for Pride & Prejudice) and movies inspired by a theme park ride (the Pirates of the Caribbean series). Jolly good show! 
19. Cameron Diaz
There’s something about this 34-year-old former model that we just like. Maybe it’s her goofball smile, or her gregarious personality, or the way she rakes in a whopping $20 million per movie. (Ranked by Forbes as the 15th-richest woman in entertainment, her net worth is estimated at $75 million.) But we mainly like her for her body. Hey, Mom told us honesty was the best policy.
18. Megan Fox
After appearing in every tween flick from Holiday in the Sun to Confessions of a Teenage Drama Queen, the proud bearer of five tattoos is set to break out in this summer’s highly anticipated Maxim Hot 100 show on VH1. Well, that and Michael Bay’s Transformers.
17. Maria Sharapova
Anna Kournikova was the perfect tennis player—except for the way she played tennis. Then along came this six-foot-two Russian sensation, who figured out a way to score some Grand Slam titles while maintaining her ravishing good looks. By 2007 she’d racked up endorsements with everyone from Gatorade to Motorola, becoming the world’s highest-paid female athlete. Yo, Maria, can you spot us a twenty?
16. Ashlee Simpson
Once dismissed as the baby sister of buxom singer-actress-divorcée Jessica, this former ballerina has finally come into her own. With two number one albums (Autobiography and I Am Me), a critically lauded run as Roxie Hart in the London stage performance of Chicago, and an altered nose, she’s become Hollywood’s hottest swan.
