John Mayer seems to have rebounded from his last celebrity breakup - and moved on to another. Mayer was spotted out in NYC last night with Cameron Diaz. "They went out to several places... It was the two of them, getting to know each other, out on the town," says a source. Diaz is in New York filming What Happens in Vegas, and has reportedly known Mayer casually for a while. "This was technically not their first time hanging out...they've hung out together with friends before. But this was the first time together like this. It's new and developing...but they really like each other and it went well," said the source. Reps for both stars have not commented.
