Kelly Osbourne & Christina Aguilera: War of Words

They’re two of the strongest personalities in Tinseltown, and it seems there’s no love lost between Christina Aguilera and Kelly Osbourne.

During a recent interview on E!’s “Fashion Police,” the British babe weighed in on Aguilera’s appearance, noting that she was a bit heavier these days.

Kelly declared, "Maybe she is just becoming the fat b***h she was born to be. I don't know. She was a **** to me. And she bought my house!”

Osbourne added, "She called me fat for so many f***ing years. So you know what? F**k you! You're fat too."

F**K U Kelly Osbourne, Christina has talent and you've got?
