The Toxic hitmaker appears briefly in a new teaser for the Tv movie, Miley: The Movement, which will air in America next month (02Oct13), and chronicles the Party in the U.S.A. singer's controversial Mtv Video Music Awards performance in New York in August (13).
Footage features Spears chatting to Cyrus in a recording studio, with the younger star explaining, "Everyone takes the Vmas so seriously, but I just wanna come out and shoot a hot dog gun."
In fact, the pop star shocked viewers with a raunchy stage routine that made Britney's decade old, showstopping lip lock with Madonna look tame. She 'twerked' and gyrated her way around the stage during the provocative performance of her song We Can't Stop and hooked up with Robin Thicke to give his Blurred Lines hit a revamp.
At one point she grinded up against Thicke's crotch while making suggestive facial expressions and sticking her tongue out.
Miley: The Movement will also feature footage from rehearsals, fan encounters and recording sessions over four months prior to the release of Cyrus' new album Bangerz.
