Katy Perry has responded to Miley Cyrus' diss about her ex-boyfriend. Perry directly mentioned Cyrus' post on Twitter on Thursday, March 6, saying that she would spank her the next time they meet. "Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see you in the UK bb!" The message was added with emojis of tongue and flag.

The stars' apparent row started after Perry made a comment about being kissed by Cyrus when she attended the former Disney star's "Bangerz" show in L.A. last month. "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 jokingly said in an Australian show on Tuesday. "God knows where that tongue has been... We don't know! That tongue is so infamous!"

Cyrus, apparently is not happy with the remark. She then took to Twitter to slam Perry. The 21-year-old star even took a jab at Perry's ex. "Girl if [you're] worried [about] where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT been," she wrote. Cyrus added in another post, "Dontchyouuuu act like you didn't lurvvvvv it."

Perry reportedly split from boyfriend John Mayer last month. Prior to having a relationship with Perry, he previously dated some celebrities such as Jennifer Love Hewitt, Jessica Simpson and Jennifer Aniston.
