Kelly Osbourne has lost about 50 pounds starting with her days as a contestant on last year’s edition of Dancing With the Stars. More confident, healthier and good-looking than ever, Kelly is now smiling and showing off her body on the cover of Shape magazine.

The mag, which is out on newsstands on November 22, carries on the cover a picture of Kelly in a red, two-piece bathing suit, which showcases her flatboard stomach and toned body.

Her fans must know that the shoot took place last month, with Kelly taking to her official Twitter page to say, once it was done, it had been an entirely new experience for her.

Accustomed to always be wearing onepieces that helped her hide her flaws and the extra pounds, Kelly had a lot of fun at the shoot – but she was also overwhelmed with joy for finally being able to do something like this.

“I just got done trying all the bikinis on I have never worn one in my life! I had a little tears of joy moment in the bathroom!” Kelly tweeted at the time.

“I cried in my interview I just can’t believe today happened it your not going to believe ur eyes! [sic]” she also wrote.

Kelly has always been very open about how hard it was for her to get in shape. However, being on DWTS gave her the motivation she needed by showing her weight loss could be achieve through workouts and eating well.

“I used to eat chips and cookies and drink soda all day long. I had to start making better choices,” Kelly said, as cited by the Daily Mail. She’s now 112 pounds, so the “better choices” are definitely paying off.

“I indulge with pizza and cheese – I love Brie – and have cookies sometimes. But now, when I’m full I stop eating! It may have taken me 26 years to figure it out, but I’ve finally learned how to do it right,” the self-confessed “emotional eater” explains.

If she stops to think about it, Kelly’s addiction to prescription pills may also have something to do with her weight, in the sense that being overweight and being constantly criticized for it made her hate herself, which, in turn, pushed her to do drugs, she says.
