Kim Porter, the longtime girlfriend of Sean ‘Diddy’ Combs, is reportedly moving out of his home despite having given birth 7-months ago.  The couple had been together for approximately 10 years… that’s if you count the time they were actually apart (a.k.a The Time Puffy Was Dating J.Lo).  When that high-profile relationship ended, Combs went right back to the woman who had already mothered his son, Christian.

After Kim delivered twin daughters D’Lila and Jessie last December, I sincerely hoped that Sean would stick by her side and marry her (not that anyone has to get married or anything).  But now rumor has it that an actress famous for her own love problems may have something to do with this latest breakup.

Page Six is reporting that Combs spent many late-nights partying with Sienna Miller instead of rocking his girls to sleep shortly after they were born.  Additionally, they recently were seen spending time together after the concert for Princess Diana.  Apparently being cheated on by Jude Law doesn’t pre-empt you from doing the cheating…

Those wondering, like me, why people find him so appealing can try watching the current season of Making the Band 4 (MTV) to figure it out.
