John Mayer and Cameron Diaz are probably banging. The two were "super flirty" and "all over each other" at New York's Bowery Hotel over the weekend. People magazine reports:

Mayer, 29, and Diaz, 34, who sat together on a couch in the back of the patio, "were laughing and talking a lot" as the waitress brought several rounds of drinks, says the source. Last Tuesday, the pair were spotted having dessert at the French-Vietnamese restaurant Indochine. "It looked like a casual date," said a source. "She was giggly. She was laughing and seemed happy." Asked if the newly-close pair are dating, a source close to Mayer tells People, "Yes, it's definitely true." (Source)

Of course she was giggling and seemed happy. She's Cameron f'ing Diaz. That's how she always acts--from weddings and birthday parties, to war memorials and Holocaust museums. I could do an hour of standup only using semaphore flags and Cameron would laugh the entire time. The only way to shut her up is to put on a Dane Cook CD. C'mon people, his jokes blow. Two million MySpace friends don't make you funny.
