Reminiscent of the headline-grabbing kiss Britney Spears and Madonna shared at the 2003 MTV VMAs, Miley Cyrus and Katy Perry performed an intimate stunt during her Bangerz tour concert in LA on Saturday.
It all started when Cyrus was singing the chorus of her latest single, Adore You.
She waved Perry over, closed her eyes, and boom - locked lips.
Fans in the audience captured the kiss for the world to see, and Miley herself shared a snap on Twitter.
It's just the latest in a string of interesting on-stage moments during Miley Cyrus' tour.
