Miley Cyrus is responding to Katy Perry’s comments about their kiss at one of Cyrus’ Bangerz tour stops recently.

After Perry said she pulled away from Cyrus when she tried to slip her the tongue, she added she doesn’t “know where it's been.”

Cyrus is clearly not happy about the comments and even dragged Perry’s ex, John Mayer into it. She took to Twitter on Thursday and wrote “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.”

She included a picture of Perry giving the interview in Australia this week with quotes underneath of what exactly she said.

As we previously reported, Perry said of their 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 added, "God knows where that tongue has been. We don't know! That tongue is so infamous!"

Perry has dated many women in Hollywood, including Jessica Simpson, Jennifer Aniston, Jennifer Love Hewitt, Taylor Swift and more.
