Kelly Osbourne: 'Fat Rehab' Rumors Are 'Stupidest Thing Ever!'

Kelly Osbourne is laughing off rumors she recently went to rehab to lose weight.

“It’s the funniest thing ever,” the 29-year-old told Access Hollywood in a new interview, rolling her eyes.

The “Fashion Police” host said she prefers to tackle false gossip immediately, but found this particular rumor hilarious.

“I’ve always confronted the rumors head on when they’re made up like that, but that one particularly just really made me giggle” she said. “Like whenever I’ve wanted to cancel something I’m like, ‘Oh sorry, I’m busy in fat rehab. I can’t go…?’ It’s just the stupidest thing ever!

“You know you’re doing well when someone’s trying to make stuff up about you,” she added.

Kelly, who is known for her fresh and unconventional hairstyles (she’s rocked both gray and lavender hues in the past), just shaved the side of head and she’s not finished with the razor just yet.

“I think I’m gonna go a little bit further with it,” she said. “I love it this way.”

Kelly, who is a paid spokesperson for Wheat Thins Popped, also has a new clothing line for women in the works, which will include sizes 0 through 24.

“I will not sell in any store if they don’t take the full size range… because let’s face it, not everyone’s a size 0 and I think the average size in America is between 14 and 18, and that’s not fair. They deserve high fashion as well,” she said. “I’ve done it in a very cost effective way and there’s a great story behind it. So once it comes out I’ll be able to tell you more, but it’s an every woman’s clothing line and I’m not trying to be the next Alexander McQueen by any means, or the next Christian Dior.”

Adding, “I’m trying to show the fashion world that it’s not one kind of woman you design for, it’s every kind of woman.”
