Britney's ex tells Hilton to stay away from Britney

Kevin Federline has personally warned Paris Hilton to stay away from his ex-wifeBritney Spears, reports say.

K-Fed, who has two children with Britney, told the hotel heiress and reality TV star to leave Spears alone, as he sees her as a bad influence.

Kevin reportedly told Paris at club Lavo in Las Vegas, that he does not want Britney to return to her troubled lifestyle after her successful return at this year's MTV VMAs.

"It was quite a chilling warning. She was quite friendly and asked how Britney and the kids are but she won’t be asking again," a source told The Daily Star.
