Justin Bieber keeps rolling out those Christmas hits!

The 17-year-old singer has just released the video for "Santa Claus Is Coming To Town" ... a song featured on Biebs' album Under The Mistletoe. The holiday track is also on the soundtrack for Arthur Christmas.

In the upbeat video, Bieber is seen working hard in what looks like Santa's North Pole workshop. With the young singer's funky 'do, a robotic-type arm and breakdancing elves ... what's not to like!

You may recall, during a recent Today Show appearance to plug his new album, Justin forgot lyrics to this song ... and repeated some lines and danced a little in the hopes that audiences wouldn't notice. We noticed, but he still rocked it!

This video follows last week's release of the "All I Want For Christmas" music video featuring Mariah Carey. Bieber sure knows how to give for the holidays.
