It seems that Miley Cyrus could not hold back at all after hearing Katy Perry's reaction to how she allegedly attempted to kiss the 'Roar' singer deeper than the usual girlfriend peck.

The two locked lips in one of the former Disney star's shows, after which Miley reportedly remarked, "I just kissed a girl, and I really liked it a lot," notes CNN.

But it appears that Miley liked the girl-to-girl kiss on her own, as Katy revealed how she immediately ended the "scandalous" lip-locking in an Aussie show.

"I went to her show, which was amazing. It is very colorful - I mean that in all ways. She has this one part where it's like a kiss cam," Katy Perry said in Aussie show, Sunrise.

"I just walked up to her to give her like a friendly girly kiss, you know, as girls do. Then she like tried to move her head and go deeper and I pulled away," the singer continued.

The 'I Kissed a Girl' hit-maker also added, "God knows where that tongue has been! We don't know. That tongue is so infamous!"

Miley, who has been known for her tongue antics, lashed back at her friend on Twitter, saying "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."

The response immediately prompted reports of the two allegedly ending their friendship but based on the singers' tweets, it looks like Miley and Katy have kissed and made up again.

After taking it on her friend's ex-boo, rumored to be John Mayer, the former Disney star tweeted a sketch of the scandalous kiss, saying "Dontchyouuuu act like you didn't lurvvvvv it @katyperry."

The 'I Kissed a Girl' hit-maker responded, "Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see you in the UK bb!"
