Kelly Osbourne's Fearless DWTS Style

Each week on Dancing With the Stars, Kelly Osbourne wows viewers with her poise, dedication and newly sleek physique. In fact, since starting the show, she's dropped 14 pounds!

"You don't automatically get skinner," Kelly tells OK! in a new exclusive interview and photoshoot. "You start to see things get a lot harder, then a different shape."

"Fashion allows you to become whoever you want to be," she says. "If I wake up and feel French, I can wear a beret and red lipstick."

Thanks to her new body, Kelly, who is engaged to model Luke Worrall, 19, has become more confident — especially with clothing.

How has DWTS changed you?

I feel clean and alive! I'm probably the healthiest I'v ever been.

Has your diet changed?

Dance partner Louis van Amstel lets me have whatever I want as long as I don't have too much. I don't feel cheated.

Do you like your DWTS costumes?

I was a bit inecure and scared to wear them, because it's stuff I've never worn before — and most likely wouldn't again. But it's about getting into the role and taking that leap of faith.

In an exclusive OK! shoot, Kelly, 25, flaunts her new look and new attitude.
