Kelly Osbourne talks Christina Aguilera: 'I was never that fat'

It's time for round 3 and this one looks like it's going to Kelly Osbourne. On Friday's (Oct. 14) episode of "Fashion Police," Osbourne took on Christina Aguilera's Michael Jackson tribute concert outfit. The outfit admittedly was not Aguilera's most flattering, but that didn't stop Osbourne from pulling punches.

"She called me fat for years. I was never that fat."

Osbourne's "Fashion Police" co-star George Kotsiopoulos blamed the outfit and softly accused Aguilera of not being a size 2/4. Osbourne quickly shot back with "trust me, I'm a 2/4. That is not a 2/4." 

It's clear that Osbourne is carrying around some baggage, previously claiming that Aguilera "called me fat for so many f------ years, so you know what? F--- you! You're fat too." 

Ladies, please. We're all beautiful, no matter what they say. Words can't keep us down.
