Justin Bieber is scheduled to perform with Boyz II Men on tomorrow night’s Dancing with the Stars. Although it’s Halloween, they’ll be singing the Christmas song “Fa la la” from Justin’s new album, Under the Mistletoe, which was released today and features 11 songs in total, including six original songs co-written by Bieber. The album also features duets with Usher (The Christmas Song), Chris Brown (Christmas Eve) and Mariah Carey (All I Want for Christmas Is You). The album’s first single, “Mistletoe,” charted at number 11 on the US Hot 100 when it was released earlier this month. A portion of the revenue from the album will go to Justin’s two favorite charities: Pencils of Promise (which builds schools in developing countries) and the Make-A-Wish Foundation.
