The past few days have been busy ones for Katy Perry. According to multiple sources, the singer was seen making out feverishly with a couple of different boys.

First up - John Mayer (germy!). Katy was spotted kissing him at Gold Bar on Friday night. Next, Russell Brand. He joked about liking her onstage at the VMAs, she took the cue and hunted him down at Lady Gaga’s after-party at Avenue in NYC.

Not only did Russell kiss Katy, according to a source, he also checked out her breasts.
