A few months ago, singer/actor Tyrese Gibson, AKA Black TY, came under fire for allegedly beating down his pregnant girlfriend. And now the gossip wire is going crazy with talk that the entertainer is dating actress Cameron Diaz.

“Looks like the tide went out and took surfer Kelly Slater with it. A Gatecrasher spy caught Tyrese Gibson and Cameron Diaz in full lip-lock at the hip L.A. club Xenii. “They made out right in front of me on the dance floor,” says the spy. They also came (and left) together to a pre-Oscars party thrown by Harvey Weinstein, Tamara Mellon and Tracey Edmonds, although Diaz’s rep tells us the two are not dating.”

Cameron’s people are denying th story.
