In the latest issue of Billboard, Justin Bieber's manager, Scooter Braun, boasts that, "vocally, his balls have dropped." Well, that much is clear on the just-leaked collaborations from Bieber's upcoming Christmas album, "Under the Mistletoe."
A bass-ier Bieber duets (and scats) with the Christmas queen herself, Mariah Carey, on a remake of her own wintery smash hit, "All I Want For Christmas Is You," which sat atop Billboard's Holiday Songs chart last year. Listen below.
Another holiday favorite gets the celeb duet treatment on "Under the Mistletoe": "Little Drummer Boy" gets Busta-fied, with a deep-voiced Bieber trading rhymes with Mr. Rhymes. Listen to the carol turned club banger below.
