Exclusive: On Set for Justin's New Christmas Video

ET's Samantha Harris got an exclusive behind-the-scenes look at Justin Bieber's new music video that will be featured on the big screen this holiday season. 

Justin shows off his drumming skills as well as his singing in the video, which will appear in Arthur Christmas, opening November 23. The 17-year-old also contributed the song -- Santa Claus is Coming to Town -- to the film's soundtrack and it's also included on his new album Under the Mistletoe, which drops tomorrow. 

The singer reveals some of his favorite duets on the new album and also shares some Christmas memories, including the celebrity he thought about kissing under the mistletoe.
