Katy Perry apparently is aware of John Mayer’s, um, reputation with the ladies. Katy is aware of it but not intimidated by it. According to Us Weekly, Katy is planning to change John. A source said:

“She doesn’t want to be just another one of his conquests.”

So what’s the plan? Playing hard to get, for one.

“She recently told John she was open to see other people,” the source reveals. According to a second insider, “Once Katy turned her back on him, he started chasing her again!”

I don’t know about this one. Changing another adult is next to impossible to do, unless he WANTS to change. Otherwise, you’re just playing games. I hope Katy understands that!
