Kelly Osbourne has blasted pop peer Christina Aguilera, though she says she wouldn’t tell it to her face, unless provoked.

“Christina Aguilera is one of the most disgusting human beings in the world. She is despicable for so many reasons. She has an amazing voice, but that doesn’t change the fact she’s one of the world’s biggest cu**s.”

“She also looks like a fu**ing drag queen!”

But would she tell Christina if she ran into her? “I don’t like arguing” she said. “I’d probably just ignore her. But if she said something to me, I wouldn’t hesitate to tell her what I think of her.”
