Diplo pretty much served as Perry's rebound from John Mayer, and reports say that she and the bad boy DJ split because he actually wanted something serious, while she wanted to hook up and date casually. (That's surprising, considering she penned Kelly Clarkson's hit "I Do Not Hook Up.")
A source told InTouch, "Diplo broke up with her because she does not want to be in a serious relationship. She's doing OK and not too sad about it. They wanted different things. She freaked out when he wanted to introduce her to his parents. She doesn't want to get married again — at least not anytime soon."
The insider added, "She wants to date and he wanted something much more serious. It was too much, too soon."
Sounds like that may have been why she and Mayer split up -- there were constantly engagement reports about the on-again off-again couple, usually because Perry would sport conspicuous rings around Valentine's Day two years in a row.
Another source claims Perry "was really into [Diplo]," but because they're both so busy the DJ didn't think it was "fair" to maintain anything serious, especially while the rainbow-wigged singer is on her Prismatic world tour.
Anyone else counting down until Katy Perry and John Mayer are back together?
