It's kinda hard to dispute claims of an alleged romance when you've been caught hanging out on video. In April 2008, X17 filmed Cameron and Gerard at Chateau Marmont in Hollywood, Calif., engaging in a little flirtatious behavior. Though the two were never caught kissing, per se, there was definite chemistry between the actors. So was this video evidence of a new love affair? While promoting the film "The Ugly Truth" on "The Tonight Show with Conan O'Brien," the actor laughed off dating rumors, saying, "On Saturday, I'm marrying Cameron Diaz. Joan Rivers will be the next weekend."
