Kelly Osbourne sure holds a grudge.
On E!’s Fashion Police Friday, the 26-year-old slammed Christina Aguilera for her weight. "She called me fat for years," Osbourne said. "I was never that fat."
Osbourne was criticizing Aguilera’s performance look at last weekend’s Michael Jackson Tribute Concert. The 30-year-old paired a pantsless ensemble with fishnet tights, heavy makeup and supersized hair.
