Miley Cyrus' duet single with Britney Spears leaked online

London, October 1 (ANI): Miley Cyrus and Britney Spears' duet single for the 20-year-old popstar's upcoming album, 'Bangerz,' has reportedly leaked online.

The version, which has been released of the single, 'SMS,' is of low quality and features many rude words as well as references to men, one night stands, sex toys and a lot of swearing, the Mirror reported.
