Kim Porter, P Diddy�s girlfriend of 10 years has reportedly called off their relationship. Could this be due to the suspicious �partying� he has been participating in with Sienna Miller recently?

Page Six claims that mother of Diddy�s three children has moved out of his apartment and has no intention of going back. A source says "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."

In December, after the birth of his twins, Diddy was reported doing excessive amounts of partying with Sienna Miller. One night she even stayed in his hotel room overnight. This past week after the Diana Memorial concert, the pair struck it up again at an after show party.

He really is a bad boy for life.
