Miley Cyrus and Katy Perry are having what professional pop culture aficionados call one awesome girl fight.

Sorry, that was out of line ... cat fight.

So some of you sickies out there may remember last month at Cyrus' concert in Los Angeles. Perry, who was in the front row, obliged Cyrus when the singer went in to give Perry a kiss. Only Cyrus appeared to try get all French on her, which Perry wasn't having and pulled away.

That's right. Katy Perry kissed a girl ... and didn't like it.

Perry recently described the incident on Australian television, according to TMZ.

"I just walked up to her to give her like a friendly girl kiss, you know, as girls do," she said, explaining how stunned she was when Cyrus went Gene Simmons. "God knows where that tongue has been. We don't know. The tongue is so infamous!"

She makes a good point. The girl is worse than a puppy.

Perry may have meant is as a joke, but Cyrus doesn't seem to be taking it that way. firing back on Twitter "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."

If she's talking about John Mayer, she kind of makes a good point, too.

We can only hope Perry isn't mature enough to let that go.
