Katy Perry and Miley Cyrus are having a little fun with their recent kiss. The two pops stars smooched at one of Cyrus' concerts in February -- and they seemed to both like it at the time.
After the lipsmack, which was caught on camera, Cyrus tweeted: "I just kissed a girl, and I really liked it a lot" -- referencing Perry's hit song.
But here's where it gets juicy: "God knows where that tongue has been. We don't know! That tongue is so infamous," Perry said before adding, "We're good friends."Cyrus apparently heard Perry's comments and decided to respond on Twitter in what appears to be a reference to John Mayer, Perry's rumored ex-boyfriend: "Girl if ur worried abt where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT...been."
