Perry shared a kiss with Cyrus during the latter's Los Angeles concert on February 22. Cyrus had motioned for the singer to come forward in the audience and shocked fans by kissing Perry full on the lips.
Apparently the kiss was a surprise for Perry as well. "I just walked up to her to give her like a friendly girly kiss, you know, as girls do. Then she like tried to move her head and go deeper and I pulled away," the singer told Sunrise.
Perry went on to say, "God knows where that tongue has been. We don't know! That tongue is so infamous!"
The singer did add that she and Cyrus are "really good friends" and that she thought the show was "amazing" and "colorful."
Cyrus has continued her girl-kissing streak since, puckering up to rapper Brooke Candy and making out with a fan last Saturday during her Las Vegas concert.
