They say what goes around comes around and Kelly Osbourne just served a big ol’ dish of whatever is supposed to come around to ‘The Voice’ judge, Christina Aguilera.

During a recent episode of E!’s “Fashion Police,” show host Joan Rivers commented that Aguilera looked like she was stuffed into Givenchy LBD whilst being pictured in Munich, Germany. To which Kelly, 26, shockingly (but not really) said “Maybe she is just becoming the fat bitch she was born to be. I don’t know. She was a c*nt to me. And she bought my house!. She called me fat for so many f***ing years. So you know what? F**k you! You’re fat too.”

In a February 2010 interview with Us Weekly, Kelly opened up about her much publicised weight issues. “I took more hell for being fat than I did for being an absolute raging drug addict,” she said. “I will never understand that … I would rather be called ugly than be called fat!'”

SMH. Talk about taking their feud to whole new level!!
