Mayorexic? John Mayer Debuts Extreme Weight Loss And Scary Slim Figure

It seems John Mayer isn't taking his split from Katy Perry well.

The "Who You Love" singer reportedly lost over 30 pounds since splitting with Perry, OK! magazine has learned.

“John thought that he had found Ms. Right in Katy, so he definitely slacked on his workouts while they were together,” a source tells OK!. “Since the breakup, he’s lost much more weight than he put on — and his friends are worried he’s going overboard.”
