Just the other day, Britney ex Kevin Federline bumped into Britney ex Justin Timberlake at a pre-Grammys party, then crossed paths with Britney ex Isaac Cohen at a Timberlake concert at Avalon. And speaking of crossing paths, Cohen told an LA radio deejay that when he was sexing with Britney, he always felt Kevin was in bed with them. (Photo: x17)
