Justin Bieber invites fans Under the Mistletoe

Pop star Justin Bieber has revealed the title and cover art for his hotly-anticipated upcoming Christmas charity album, reports HitFix.

The new holiday album will be titled Under the Mistletoe and will hit stores November 1, with an early iTunes download available October 13, Bieber told fans via Twitter. "This is not your normal christmas album," he added.

Instead of covering the traditional classics, rumors suggest that the LP will consist entirely of original songs. A number of musical guests have been tagged to feature on the album, including Usher, Boyz II Men, The Band Perry, and some mysterious legendary performer.

Still refusing to reveal the special guest’s name, both Bieber and his manager have been teasing fans about the epic track: "cant believe it … completely #HONORED. I think people are going to be shocked. I was," Bieber wrote last week.

Fans may soon have their answer, however, as the pop star has promised to unveil the name of the final guest today. "well i got 1 more guest…" he wrote yesterday (October 2). "…and i will tell you who it is 2morrow."
