Oh no she didn't!
"I just walked up to her to give her like a friendly girly kiss, you know, as girls do," Perry said, adding, "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!"
Well it looks like Cyrus didn't appreciate that dig.
The "We Can't Stop" singer posted the following message on Twitter earlier today:
"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 added, "Dontchyouuuu act like you didn't lurvvvvv it."
Is there no girl code anymore? Can't all the pop stars just get along?!
Perry and Mayer broke up shortly after it was announced that the she was about to embark on a seven-month world tour, which is set to begin in May.
E! News learned that despite Mayer's "wandering eye," trust issues weren't what ultimately lead the two to part ways.
Yikes…talk about rubbing salt in the wound!
