Diddy threw a birthday party for his baby’s mother and longtime pal Kim Porter. Word is that even though they’ve both decided to go their separate ways they’re still friends.

Guess who wasn’t invited to the party – Diddy’s girlfriend R&B singer Cassie.

Here’s how it’s being reported elsewhere:
Diddy and Kim Porter have had a longtime on-again off-again romance – but the pair celebrated in style together when the music mogul threw an intimate birthday bash for her in West Hollywood Monday.

Nearly 30 guests, including Grey’s Anatomy star Ellen Pompeo and husband Chris Ivery, co-star Sara Ramirez and reality TV’s Lisa Gastineau, gathered at Murano Restaurant & Lounge to celebrate Porter’s 38th birthday.

Porter – the mother of Diddy’s nearly 2-year-old twin girls and 10-year-old son – arrived fashionably late to the restaurant, which was filled festive with red balloons and streamers. The night’s soundtrack was a mix of old school 70s R&B prepared by Murano owner Sandy Sachs.
You gotta give it to Diddy. As many baby’s mama’s as he’s got and he seems to get along with all of them
