Kelly Osbourne used to be terribly fat while Christina Aguilera was thin as a blade of grass. Now the two have seemingly switched places, and Kelly is not shy about letting the pop singer know about it.
On an episode of E!'s "Fashion Police," host Joan Rivers said Aguilera looked "stuffed into" a Givenchy dress at an event in Munich, Germany last month.
“Maybe she is just becoming the fat bitch she was born to be," said Osbourne. "I don’t know. She was a c**t to me... She called me fat for so many f***ing years, so you know what? F**k you! You’re fat too.”
