Katy Perry has threatened to give her friend Miley Cyrus a 'spanking'.
The pop stars shared an infamous kiss at one of Miley's recent concerts, and during an interview this week, Katy joked she was concerned where the Bangerz singer's mouth has been.
Miley shot back Thursday on Twitter with a saucy message, which referred to Katy's rumoured ex-boyfriend John Mayer.
And a few hours after Miley's tweet, Roar singer Katy told her peer to expect punishment.
'@MileyCyrus Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see you in the UK bb!' she joked to her over 51 million Twitter followers.
The pop stars locked lips when Katy attended the Wrecking Ball singer's show in Los Angeles late last month.
And during an appearance on Australian TV programme Sunrise this week, the Prism star said she was stunned to receive the front row smooch.
'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,' Katy said.
'God knows where that tongue has been. We don't know! That tongue is so infamous!'
But her comments got a quick answer from Miley.
'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 (sic),' Miley wrote, dragging in Katy's rumoured former flame John, who is known for serially dating a slew of Hollywood beauties in the past, including Jessica Simpson, Jennifer Aniston and Taylor Swift.
