Kelly Osbourne and Christina Aguilera's feud goes way back. It started years ago when Kelly said she wanted to stab herself after listening to the singer's Christmas album and then at the 2003 MTV Europe Awards, Christina was seen throwing darts at pictures of Kelly.

The tension heated up again recently when Kelly teased Christina about her weight gain. Speaking on her show Fashion Police, Kelly mocked her fuller figure, declaring, "She called me fat for years... I was never that fat!"
