As opposed to the 'I Kissed a Girl' lyrics, Katy Perry appears to not like how Miley Cyrus kissed her during her 'Bangerz' concert in Las Vegas, Nevada.

While singing 'Adore You', Perry gave the former Disney star a simple peck to which Cyrus responded with a passionate kiss. John Mayer's ex-girlfriend reportedly pulled back for she was quite unsure of the 'Wrecking Ball' singer's tongue.

"That tongue is infamous. I don't know where it's been," she told an Australian radio show.

Liam Hemsworth's former lady love slammed back through her Twitter page. She apparently wrote a tweet pertaining to Perry's comment about her tongue:
