Miley Cyrus Lashes Out At Katy Perry on Twitter

Katy Perry, Miley Cyrus

Months after lashing out at Sinead O'Connor on Twitter, Miley Cyrus has now sunk her teeth into another female musical artist -- this time, pop superstar Katy Perry.

It all started on Feb. 22, at Cyrus' Bangerz tour show at the Staples Center in Los Angeles, where the "Wrecking Ball" singer spotted Perry in the front row, hopped offstage and leaned in for a quick kiss. Apparently the kiss was a little too hot-and-heavy for Perry, who declared in a new TV interview during her trip to Australia, "I just walked up to her to give her a friendly girly kiss. You know as us girls do. And then she like tried to move her head and go deeper and I pulled away. God knows where that tongue has been!"

Those recent comments were spotted by Cyrus and tweeted out as a captioned photo on Thursday afternoon (Mar. 6), with Cyrus adding her own thoughts on the matter. "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 emoji] been," Cyrus quipped, referring to Perry's ex-boyfriend, John Mayer (who has also dated Taylor Swift, Jessica Simpson, Jennifer Aniston and other female celebs).

Minutes later, Cyrus posted a drawing of Perry and herself locked in a passionate kiss, with the caption, "Dontchyouuuu act like you didn't lurvvvvv it." Perry has yet to respond on Twitter.

While Cyrus' arena tour began last month, Perry's PRISMATIC trek kicks off in May. Both pop superstars enjoyed No. 1 hits last fall ("Roar" for Perry, "Wrecking Ball" for Cyrus), with Perry earning another with "Dark Horse" earlier this year.
