It's being reported that Cameron Diaz has reunited with rumored flame Sean "Diddy" Combs, and a source tells Us Weekly that the two "had their hands all over each other" when they dined at Catch in New York City on October 24. When the duo lunched at Scarpetta in Beverly Hills last Friday, they were "making out, acting romantic," says another source. The mag claims Diddy has been "her off-and-on hookup since 2008," and a source added, "When she's single, she'll booty call him."

Of course, Diddy is still dating R&B hottie Cassie, and Cameron's rep tells X17online, "Cameron and Sean are longtime friends and fans of one another's work. They have been seen together recently because they are developing a film project. They are not romantically involved." And People mag reports that it wasn't exactly a romantic lunch date -- though the two were alone for the first part of the meal, they were joined by a man who appeared to be a business associate.

Hmm, what do you think is going on? Is Cameron really getting down and dirty with Diddy?!
