Miley Cyrus is firing back at Katy Perry after Perry joked about the singer’s ubiquitous tongue during a radio interview.

As reported, Perry was asked about Cyrus kissing her at her BANGERZ concert, and responded, “I walked away. I was like, that tongue is infamous. I don’t know where it’s been.”

Cyrus was apparently not happy about Perry’s comments, and responded by taking a shot at the star’s ex John Mayer.

The “Wrecking Ball” singer tweeted on Thursday, “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,” along with a link to Perry’s comments.


Cyrus then added in a more playful tone:

Perry and Mayer just broke up last week.

What do you think of Cyrus’ response to Perry?
