UPDATE: Katy Responds to Miley's Kiss Diss


Miley Cyrus isn't afraid to go there with Katy Perry!

After Katy Perry had less than kind words for Miley Cyrus regarding their now infamous kiss at her Bangerz concert in Los Angeles in February, Miley is hitting back where it hurts -- taking a dig at Katy and her reportedly now ex-boyfriend John Mayer.

It all started with Katy's appearance on Australian talk show Sunrise Tuesday, when she was asked to comment on her and Miley's much-publicized kiss.

"I just walked up to her to give her like a friendly girly kiss, you know, as girls do, and then she like tried to move her head and go deeper and I pulled away," she said. "God knows where that tongue has been. We don't know! That tongue is so infamous!"

Not surprisingly, Cyrus wasn't too pleased, and responded Wednesday.

Clearly, Miley's alluding to the reports that Katy has split with her on-and-off boyfriend -- and notorious serial dater -- John Mayer.

But Katy appeared to have a sense of humor about the harsh tweet, responding directly to another Miley tweet, claiming the I Kissed A Girl singer "lurvvvved" their smooch.
