Even more details about Justin Bieber's holiday set 'Under the Mistletoe' have surfaced. The cover is out and The Biebs himself tweeted that the Christmas album will feature a collaboration with his pal and mentor Usher. This shouldn't come as a shock to anyone, since The Biebs and Usher are down for life.

The Biebs fired off a tweet on Monday, letting the legion of Beliebers know that he just wrapped a track with the R&B crooner in the studio. He posted: “just finished a late nt in the studio for the christmas album…it is OFFICIAL…my big bro @UsherRaymondIV is on the album with me! #EPIC.”

The Biebs didn't reveal any other crucial details about the "#EPIC" song that he and Usher worked on. The album is due out on Nov. 1 and $1 from every copy of 'Under the Mistletoe' that is sold will be donated to charity.

The Biebs clearly understands that Christmas is a season of giving and helping your fellow man and you can do so by injecting a little fun into the mix, courtesy of brand new holiday songs.
