According to a well-placed source at Bad Boy Records, rap mogul Sean Combs really is dating actress Cameron Diaz. As you know, Ms. Diaz has run through every available male bachelor in Hollywood. So it should come as no surprise that she’s sampling the dark meat.

The couple continue to insist that they’re “just friends”, but they were seen tonguing each other down inside the Dream Downtown Hotel in New York last weekend. The 39-year-old actress and the 42-year-old rapper were caught ‘making out like teenagers’, according to Life and Style magazine.

This isn’t the first go-round for Diddy and Cameron. People.com reports that Sean and Cameron first got together back in 2008 after meeting at the Oscars. But Cameron reportedly told Sean to get back to her when he loses his old baggage, aka Kim and Cassie.

My source tells me Mr. Combs is “getting serious” about Ms. Diaz, whom he has a cute pet name for and everything. “Getting serious” is code for making sure Cassie doesn’t pop up whenever Cameron is around.

My source says he hasn’t seen Sean’s other concubines, Kim Porter and Cassie, around Sean’s NY digs “in a while”. He says Cassie has gone back into the studio to revive her recording career because she sees the writing on the wall and she’s tired of being Sean’s “rebound chick.”
