Part II

Did Kevin Federline give Britney Spears a lecture on the importance of car seats during Kanye West's pre-Grammy performance in L.A. Monday night? The Insider reports the down-market duo didn't appear to be having much fun at the concert, which took place just hours after paparazzi caught Brit zooming along the Pacific Coast Highway in Malibu with future tell-all author Sean Preston on her lap. Britney and Kevin "were obviously bickering during Kanye's first three songs," a spywitness says, although they reportedly made up before the night was over.
