"As bad girl Blair Waldorf in this year's breakout hit, 'Gossip Girl,' Leighton Meester has stolen the spotlight with her mind-blowing good looks and amazing performance," said FHM Online U.S. Editor JR Futrell.

Also making the list are Hayden Panettiere ("Heroes"), Madeline Zima ("Californication"), Deanna Russo ("Knight Rider"), Jamie-Lynn Sigler ("Entourage"), Jaime King ("Gary Unmarried"), Summer Glau ("Terminator: The Sarah Connor Chronicles"), Kaley Cuoco ("Big Bang Theory"), Dania Ramirez ("Heroes") and Eva Longoria Parker ("Desperate Housewives").
