There is no doubt that exercise pays off as Kelly Osbourne has been looking FIT in both senses of the word, since she took part in the US show Dancing With The Stars.

But some are not content with the fact Kel looks amazing and have to specualte that the TV personality has had cosmetic surgery.

The reality TV star recently lost 40lbs (2.9st) but insists that it was down to exercising frequently and maintaining a healthy diet.

Kel wrote in Closer magazine, "I'm so angry there are rumours going around that I've had fillers in my lips, or liposuction on my legs.

"Someone even said I've had a gastric bypass! I have 100% not had any of that. I've lost weight from my face, and that's why it looks different.

"I can say with confidence that the only time I've been in a plastic surgeon's office was with my mum [Sharon], and though I wouldn't rule it out when I'm older, right now I couldn't even do it if I wanted because of my past addictions - I couldn't take the medication they put you on."

She added, "The rumours are ridiculous. They send out the wrong message because I've shaped up working hard for months - it wasn't a quick fix!"

We think you look fabulous Kelly and totally believe it was down to hard work. Dancing With The Stars isn't for the faint hearted, as this year's contestants will soon find out!
