Justin Bieber previews his new song on Instagram

Pop star Justin Bieber has posted on Instagram, a video featuring a very brief snippet of the track.

In the video, Bieber is seen going shirtless as he busts out some moves alongside choreographer Nick Demoura while the track is played in the background.

There is still no word on what the title of the song or if it's really a cut off 'Purpose', which is due out on November 13.
