We thought those rumors of a romance between John Mayer and Cameron Diaz had subsided after he started hanging out with Friday Night Lights star Minka Kelly, but it turns out that the musician might be more of a player than we realized. According to Us Weekly, John and Cameron were looking very cozy last Friday in NYC and were all over each other kissing, hand-holding, and dancing. Apparently he even went so far to tell his friends that he's single and Minka's not his girlfriend. Minka looked pretty happy last night after hitting up the Waverly Inn and Butter with John, so we're not sure if we believe these rumors just yet. However, we will say that no matter how hot John is it right now, he'd be a fool to let both of these gorgeous ladies slip through his fingers.
