Think Kelly Osbourne is going to apologize to Christina Aguilera for bashing her body? Fat chance. The co-host of E's Fashion Police tells Glamour magazine that she meant what she said when she called The Voice judge "fat." In the upcoming issue of the magazine, the 27-year-old continues her tirade against her famous foe. In the article about body confidence, Osbourne tells readers to tune out critics. She also points out that what goes around comes around. Osbourne says, "Sometimes it's other people's voices you have to shut out. That's what happened with me and Christina Aguilera, which people don't understand. She called me fat for years. One night on Fashion Police I said, 'F**k you. Now you're fat too.' And I'm sorry, but I stand by that. I make a point of the show never to say anything about anybody that I wouldn't say directly to their face. I'm famous, and she's famous; it doesn't mean I can't stand up for myself." Beating a dead horse even more, Osbourne promises it's the last time she will revisit the feud between her and the busty blonde. She adds, "I took it for 10 years and finally decided to be like, 'You know what? I'm done.' And that's the last thing I will ever say about it." Although Osbourne acknowledges she is far from perfect, she tells Glamour she's happy with herself, "Even now I don't consider myself skinny. But I have put a lot of hard work into my body over the years, and in the process, I've really learned to love myself."
