Federline blasted by ex

Kevin Federline's ex girlfriend has spoken out about the collapse of his relationship with Britney Spears.

Kerri Whittington was engaged to be married to the dancer, and claims she wouldn't put it past Federline to have cheated on the singer. Drawing on her own experiences, she has branded him a cheat and admits she feels for Britney.

She said: "It wouldn't surprise me if he cheated on Britney Spears. He was forever in Vegas and partying with his buddies and girls. There are more than enough stories of him getting close to strippers."

Whittington also voiced her opinion on Federline's solo career, laughing: "(It's) a joke. He's horrible. He's an embarrassment."
