Kelly Osbourne is not backing down when it comes to her crusade against Christina Aguilera.
A few months ago, Osbourne, 26, called Aguilera, 30, a "fat b****" on E!'s Fashion Police. Over the weekend, Police co-host George Kotsiopoulous defended Aguilera's weight gain, saying she is "still probably a size 2/4" despite her poor outfit choice.
But Osbourne fired back, saying, "Trust me. I'm a 2/4. That is not a 2/4. ... She called me fat for years. I was never that fat."
Aguilera has faced criticism for her weight gain in recent months. Below is a picture of her in September with son Max.
Osbourne has struggled with her weight over the years, but since appearing on Dancing with the Stars in 2009, she has kept off the 50 lbs she lost.
