No, our headline isn't implying that Diddy and Kim Porter are having children out of wedlock again.
But the music mogul's baby mama did show up for his 38th birthday party this week in Miami, looking rather pleased to be there. We wonder if Sarah Chapman was also invited.
When it comes to getting along with an ex in a mature, friendly manner, who would have thought the best role models would be Diddy and Porter, and Kevin Federline and Shar Jackson?
We hope Paul McCartney and Heather Mills are paying attention.
