Where You've Seen Her: Leighton bounced between TV guest spots and direct-to-DVD flicks before scoring a high-profile gig as the snobbish but sensitive Blair Waldorf on Gossip Girl. When not flaunting the richest-sounding name in the world, she can be seen in Country Strong as beauty pageant queen-turned-aspiring country singer Chiles Stanton. The film expands to wide release this Friday, and we can't wait to enjoy the panoramic view. Nashville never looked so good! (Apologies to Toby Keith.)
What Sex Tape?: "[The tape] is not real, so it makes me sort of sad. It's unfortunate that it got carried as far as it did. I feel like my friends are in a cult because we're like, 'No outsiders!' I've never been crazy. I'm a very good girl, to be honest. I don't do anything to hurt anybody. Honestly, all I ever do is work." —Harper's Bazaar
