The pop icon slipped into a tiny bikini to expose her killer body, writhing around the floor to the soundtrack of Nathaniel Rateliff & The Night Sweats' S.O.B.
While it is unknown what the video is for, it is believed the clip may be taken from her upcoming revamped Piece of Me show.
Since kicking off the concerts in December 2013, Britney has performed the same set over and over again.
