Kelly Osbourne Call's Christina Aguilera "A Fat Bit%h" Again!!

Kelly Osbourne has once again slammed Christina Aguilera over her weight gain. Just two months ago the 30-year-old called the singer a "fat bit%h".

This all went down on E!’s Fashion Police Friday, co-host George Kotsiopoulous defended Christina’s unflattering get-up at last weekend’s Michael Jackson tribute concert. He told Osbourne that she is‘still probably a size 2/4′ despite her poor outfit choice.

But kelly had this to say

"Trust me, I’m a 2/4. and that is not a 2/4."

Ouch!!!!

She continued: ‘She called me fat for years. I was never that fat.’
