Fashion Police co-host Kelly Osbourne recently called The Voice judge Christina Aguilera "fat" on her TV show -- and she's sticking by her statment! In fact, she even told Glamour magazine that she would say it again -- to Christina's face! Could this be the beginning of a new celebrity feud?!

"She called me fat for years," Kelly said. "I said,'[expletive] you, now you're fat, too! ... Now you know how it feels!' I'm sorry, but I stand by that." Sounds like Kelly's trying to give Christina a taste of her own medicine! And, she said, she would even spoon-feed that medicine to Christina directly! "I make a point on the show never to say anything about anybody that Iwouldn't say directly to their face. I'm famous and she'sfamous. It doesn't mean I can't stand up for myself. I took it for 10 years,and finally decided to be like, 'You know what? I'm done.' " 

We're glad Kelly is standing up for herself, but maybe there's an, um, gentler way of going about it?

Kelly recently lost about 50 pounds and is looking totally fantastic. But she admitted that the scars of being called fat all those years have stuck with her. "I didn't say I wasn't fat," she said."You will always see in yourself what people used to bully you for. ...Everyone called me Kelly Smelly with the Big Belly Whose Dad's on the Telly. Ithurt so badly to be judged like that. Even now, I don't consider myselfskinny."

Hopefully these two ladies will make up soon! In an industry filled with too-thin girls battling eating disorders, it doesn't really do anyone any good to be calling the more "healthy" looking women mean names!

Do you think Kelly is justified in calling Christina fat? Or should she apologize?
