Justin Bieber duets with Christmas queen Mariah Carey on a “SuperFestive” version of her classic “All I Want for Christmas Is You,” which was released when Justin was less than a year old. The remake, featured on his holiday album Under the Mistletoe, stays true to the original, with Mariah opening the song and the teen idol coming in on the second verse.

The pop diva suggested that they do a duet after Justin approached her with a separate Christmas collaboration. “I was very honored,” he told “Access Hollywood.” I really wanted to do the song and I couldn’t do it better than her. To have her on the song with me, it gives me the stamp.”
