Newly Slim Kelly Osbourne on Cover of 'Shape Magazine'

Kelly Osbourne is enjoying the results of her newly slim body, according to UsMagazine.com. The celebrity lost 48 pounds after competing on last season’s Dancing with the Stars.

"I just shot the cover of Shape Magazine, which was such an incredible experience," 25-year-old Osbourne told Us at Teen Vogue's 8th Annual Young Hollywood party in Los Angeles Friday. "I have never worn a bikini in my life before yesterday."

Osbourne, who now weighs 112 pounds, became emotional after seeing the photo of herself in a bikini.

"I cried when I saw the picture," she said. "Everyone that was there, we all just burst into tears. It was a thrilling experience."

Osbourne works with trainer Sarah Hagaman and exercises at least 30 minutes a day to stay fit and healthy.

The star told Us magazine that since her weight loss, she has been able to fit into designer clothes.

“Now every designer will send me anything that I want, and I can’t believe that I am in this situation,” Osbourne explained. “I opened up all of these zip bags last night from Marchesa — off the runway — and I can’t believe that it fits me.”
