Justin Bieber's 'Under the Mistletoe' is finally upon us, landing tomorrow, Nov. 1, like freshly fallen snow. In honor of this momentous holiday occasion, The Biebs released a TwitVid of him in the studio, with his mentor (and collaborator) Usher and producer Pharrell.

The dudes are in the studio, with a baseball capped Biebs leaning on the console. Usher is to one side with his feet up, and Pharrell to his other, topped by a quirky captain's hat. They all look chill, relaxed and easy going, happy that the finished product lands tomorrow.

However, there's a key moment in which Pharrell says he is impressed with The Biebs' vocals. If you've heard 'Under the Mistletoe' tracks -- and no doubt, you have, thanks to PopCrush's song reviews -- you'll instantly notice that the Biebs' vocals are lower than they were two years ago as his voice deepens with age. Usher, like a good papa bear, reminds his protégé that Pharrell's words are a huge compliment and that people are buzzing about how his voice has changed and has risen as he ages.

This is no ordinary holiday album. The Biebs is stepping into a whole new (my) world.
