Katy Perry and Miley Cyrus have been poking fun at each other on Twitter. It all started when Katy guested on Australia’s morning program, Sunrise, where the interview led to the discussion on her recent kiss with Miley in one of her shows. The Roar singer was in Australia to promote her upcoming Prism tour.

The singer said that she attended one of Miley’s shows and saw a kiss cam. She wanted to give Miley a girly and friendly kiss. However, Miley moved her head and went deeper into the kiss and Katy pulled away. She ended the statement by saying “God knows where that tongue has been.” Katy also said that Miley’s tongue was infamous.

A couple of days after Katy’s interview, Miley tweeted screenshots of the interview with the caption “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.”

Miley may be referring to John Mayer, who has dated a string of personalities including Jennifer Aniston, Jessica Simpson, Heidi Klum, and Taylor Swift. She may also have been referring to Russell Brand, Katy’s ex-husband, who has confessed to being a sex addict.

Fans of the two singers were not sure if Katy and Miley were having a real girl fight about what Katy has said on her interview, or if they were just joking around.

A few days later, Miley has posted an illustration of the kiss tagging Katy on twitter. “”Dontchyouuuu act like you didn’t lurvvvvv it @katyperry,” Katy then tweeted back saying “Oooo gurrrl I’m gonna give you the BIGGEST spanking when I see you in the UK bb!”

Apparently, the two were just having fun with each other on Twitter and still remain good friends despite the things that were said.
