Diddy’s girlfriend of ten years and the mother of three of his children, Kim Porter, has moved out of their apartment and has purchased a home in Beverly Hills. She is said to have left the mogul with the overblown ego, and it seems more than overdue. Diddy was photographed after spending the night with Sienna Miller this January, and was seen out late with her late several times, which was just a few weeks after Porter gave birth to his twin daughters.

Sources inside Combs’ camp told Page Six that Porter moved out of his apartment here and she isn’t going back.

“Kim is in Louisiana filming a movie right now, and when it’s done she’s moving to L.A.,” the insider said.

Porter has already bought a posh pad in Beverly Hills for her and her four children - three of whom, Christian, 10, and twins D’Lila and Jessie, 7 months, are Diddy’s.

“She is focusing on her career as a model and actress and raising her children,” our source said. “They are the best of friends, but they just can’t be together right now.”

Diddy is said to be paying off an Atlanta woman who had his secret love child last summer, and he also was rumored to be having an affair with Aubrey from Danity Kane. He is though to have recently rekindled his close friendship with fashion-challenged Sienna Miller, and the two were seen hanging out together last weekend at an after party for the Princess Diana memorial concert.

Porter has a burgeoning film career and now that she’s tasted freedom she probably realizes she doesn’t need to keep hanging around cheating Diddy. It’s not like she’s going to be hurting for money. Diddy already pays her $32,000 a month in child support for his 8 year-old son with her, Christian, and add some cash for their infant twins and she’ll be doing fine.
