As we said, yesterday we reported that Katy commented on her kiss with Miley during a stop on her Bangerz tour, saying, “God knows where that tongue has been.” We’re not really sure if Katy was joking or not, but it didn’t take long for Miley to fire back, calling out KP’s ex John Mayer. “Girl if ur worried abt where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT tongue been,” she wrote. She also tweeted a drawing from a fan of their kiss, saying, “Dontchyouuuu act like you didn't lurvvvvv it @katyperry.”

Ouch! Bringing up John after him and Katy just broke up? Yikes! Katy responded to Miley’s call-out to John, tweeting, @MileyCyrus Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see you in the UK bb!” It doesn’t seem like Katy is too upset, but it definitely sounded like Miley was a little mad, right?!
