Proving that she too can play the field, Katy Perry has moved on from Riff Raff to a new guy. According to Page Six, Katy Perry is hooking up with DJ/producer Diplo. The two were seen canoodling backstage at Coachella, with a source saying:

“It was very obvious that Katy and Diplo were together. They seemed inseparable and at one point they were seen getting onto her bus together.”

Who's next, Katy? Who's next?
