They've never gotten along so it's no wonder Kelly Osbourne had more inflammatory remarks about Christina Aguilera on this past Friday's episode of E!'s "Fashion Police."
The 26-year-old former drug addict took aim at the "Ain't No Other Man" songstress' appearance during the recent Michael Jackson Tribute Concert in Wales, UK.
Kelly jabbed, "She called me fat for years. I was never that fat," referring to Christina's plump appearance in hotpants and fishnets onstage.
Joan Rivers chimed in, "Lady Marmalade got into the peanut butter again," while George Kotsiopoulos added, "I'm looking at this and thinking, 'Well, she's put on weight. This just isn't flattering.' But this is just a crappy outfit, regardless. No matter what shape your body is in, it's just bad."
