You may still be dreaming up the perfect Halloween costume (pro tip: buy that Drive jacket today, before they’re sold out), but young Justin Bieber is already decking the halls. Today, two pieces of holiday cheer from Canada’s Finest: first, the news that he’ll be partying with Lady Gaga in Times Square for Rockin New Years Eve; and second, the debut single off his upcoming Christmas album, Under the Mistletoe. Since Vulture prefers to celebrate New Year’s Eve with giant neon hamster balls and functional eardrums, we’ll draw your attention to “Mistletoe,†an original track that Bieber first performed in Rio last week. Early Christmas observers who also enjoy Jack Johnson are in luck; Biebz went way mellow for this one, like he maybe wrote it on a beach in between photo ops with Selena Gomez. (Sample lyric: “I should be chillin’ with my folks, I know / But I’mma be under the mistletoe Â… Shawty, with youâ€) If you’re one of the many fans monitoring his vocal register, pay special attention to the bridge, in which Biebz gives the Wise Men a very deep (for him) shout-out. We can only assume that by the time the Boyz II Men single drops, Justin will be singing bass along with the “End of the Road†talking guy. [Wrap and Complex]
