Pop singer Kevin Federline has warned Paris Hilton to stay away from ex wife Britney Spears.

Hilton and Britney were virtually inseparable after the singer filed for divorce from Federline. They partied hard in Las Vegas and Los Angeles.

Britney's ex-hubby bumped into Hilton at the opening of Las Vegas's Lavo Restaurant and nightclub at the Palazzo. And he politely asked her to stay away from his ex-wife for the sake of their kids, reports new-magazine.co.uk.

Federline expained that Britney is getting over her recent troubles and he doesn't want her to return to her wayward past.

A source said: "It was quite a chilling warning. She was quite friendly and asked how Brit and the kids are. She won't be asking again."
