Seven months after welcoming twins with Sean "Diddy" Combs, his longtime girlfriend Kim Porter has reportedly moved out of his apartment - for good. "Kim is in Louisiana filming a movie right now, and when it's done she's moving to LA," says an insider. "She is focusing on her career as a model and actress and raising her children. They are the best of friends, but they just can't be together right now." Porter has already bought a Beverly Hills home for her and her four children, 3 of whom call Combs dad. Rumors of problems between the pair began circulating earlier this year when shortly after the birth of his twins, Combs was seen out partying every night with Sienna Miller.
