Kevin Federline fights with WWE star

Kevin Federline was booed out of Monday Night Raw in L.A., when he stepped into the ring with World Wrestling Entertainment star John Cena,he was trying to promote his new album 'Playing With Fire'. Unfortunately, the want-to-be rapper didn't quite get the response he was hoping for from the audience.

Cena helped out as much as he could, act out an exchange of words with K-Fed, which ended Federline on his back by Cena's signature move - the F-U slam. That's when the crowd went wild for Cena beating the rapper. K-Fed's posse: Three 6 Mafia, Jackass stars Steve-O and Chris Pontius, Nick and Aaron Carter, were there to support him and get him home in one piece.
