Katy Perry was recently dumped by John Mayer after a couple of months of casual dating, but now sources tells how badly John ended things with Katy: "John got tired of Perry's hard partying and decided to pull the plug. He dumped her over email. She was furious and really hurt", the source reveals. "She was into him, but he wasn't feeling it." Hey John, that was reeeally low, even for you it was crazy low. We totally understand Katy, we'd be crushed too if we got dumped so suddenly over email! (thesuperficial)
