Does John Mayer emit some sort of hypnotic musk that paralyzes the fight-or-flight response in a woman's brain? Despite such romantic atrocities as giving a sidewalk press conference to announce he'd dumped Jennifer Aniston, calling ex-girlfriend Jessica Simpson "sexual napalm" and whining that he was "really humiliated" by Taylor Swift's confessional "Dear John" song, he somehow ensnared Katy Perry in his tangled web.
In July, they were spied enjoying affectionate dinners out in Los Angeles and tangling tongues during a pool party. But by September, they were kaput, ostensibly because his interest waned after he made his conquest.
Cut to a few weeks later, and Katy and John were once again spending time together, with a source telling Us Weekly, "She told him she just wants to have fun."
