K-Fed tells Hilton to leave Spears alone

Kevin Federline has personally warned Paris Hilton to leave Britney Spears alone, reports say.

Federline has two children with Spears and sees the hotel heiress as a bad influence on his ex-wife.

He reportedly had strong words with Hilton at a club in Las Vegas after Spears's successful return at this year's MTV Video Music Awards.

A source told The Daily Star: "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."

Spears and Hilton were frequent faces on the LA party scene in 2006.

Federline was recently named Father of the Year by a Las Vegas club.
