Britney Spears kfedbritparis.jpg

It's time to clear up another rumor!

So you may have heard that KFed cornered Paris Hilton in Las Vegas this weekend and told her to stay away from Britney, well ...

The story goes that Brit's ex bumped into Hilton at LAVO in Sin City and asked Paris to stay way from Brit for the sake of their kids -- don't believe everything you read.

"The story is ridiculous," a source close to BOTH Paris and Kevin tells X17online exclusively.

"Paris was in town with her boyfriend and sister to go to a charity event at the Nevada Cancer Institute and the LAVO grand opening," the source told X17. "She never saw or spoke with Kevin Federline at all. The whole story is complete nonsense. Kevin would never say anything like that."

Story sounded kinda fake in the first place, didn't it?!
