Bieber spends the rest of the time, appropriately, as a mannequin in said store, though it is unclear if he's sporting consumerist pleasures for the Men's or Women's Apparel department.

The video premiered tonight (Nov. 30) on NBC during the tree lighting ceremony at Rockefeller Center in New York.
