Think trying on bikinis alone in the dressing room is intimidating? Take a walk in Kelly Osbourne's Uggs. The TV personality-she's currently dishing the dirt on celebrity style on E!'s Fashion Police-arrives at the SHAPE cover shoot, sees the room full of gorgeous (but skimpy) suits and practically faints! "I've never worn a bikini in my whole life," she says, holding a red one up to her newly slim body. "Am I really about to bare all to the entire world? I'm so nervous!"

For the first time ever, Kelly Osbourne reveals her brand-new bikini body and tells us how she lost 50 pounds, got fit, and gained confidence-the healthy way.

Kelly talks about emotional eating, Dancing with the Stars, and what really helped her lose weight.
