Singer Miley Cyrus has slammed Katy Perry over comments she made about the kiss they shared at the Wrecking Ball singer's concert last month (Feb14).

The pair hit the headlines in February when Miley locked lips with Perry during her concert in Los Angeles.

After the smooch, Perry revealed Cyrus was hoping to steal a more intimate kiss from her, but she pulled her head away.

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

Perry added, "God knows where that tongue has been...We don't know! That tongue is so infamous!"

Now, Cyrus has hit back at the Roar hitmaker for her remarks in a tweet that reads: "Girl if ur worried abt (about) where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT been."

She adds, "Dontchyouuuu act like you didn't lurvvvvv (sic) it @katyperry".

Perry reportedly ended her relationship with singer John Mayer last month (Feb14).

He has been previously dated a number of celebrities, including Jennifer Aniston, Jessica Simpson, Jennifer Love Hewitt and Taylor Swift.
