Why do all good things come to an end? The new hot couple, Katy Perry and John Mayer, are over before they were even official! Katy and John have been casually dating for a couple of months, but now their split is official: "She's really upset about it", an insider tells. "She is making it seem like it wasn't serious with John, but she is hurt", the source continued. Well, summer is coming to an end and so does all the summer flings. Too bad though, we'd love to see them as a couple again! (usmagazine)
