As it turns out, Britney Spears also likes it rough. In this new version of Rihanna's hit "S&M," Britney drops an all-new verse in which she sings, "Tough, I don’t scream mercy / It’s your turn to hurt me” and “If I’m bad, tie me down / Shut me up, gag and bound me.”
Britney and Rihanna trade off lines in the second half of the song, but the music is otherwise identical to the version from Rihanna's album LOUD. It's a thrill to hear these two pop icons together on a track – it's kinda like when superheroes team up.
