In a game of two can play the same game, and in retaliation of Katy Perry banging Riff Raff we're sure, John Mayer decided to get Katy Perry out of his system by having a go at Kelly Monaco. According to a source who tells Perez Hilton, except that it was also probably while he was with Katy Perry:
"[John and Kelly] hooked up immediately. She was open to the things that John's into, like sexy toys, tying each other up and threesomes. He couldn't get enough. Kelly was still on his mind. He would text her and try and get her to meet him either at his place in L.A. or a hotel out in the Valley ... Katy found texts on his phone. She was devastated and realized he's a sex fiend who isn't capable of telling the truth."
But didn't John Mayer propose to Katy Perry?
