If fans want more of One Direction, they're in luck! The boy band is also getting ready for their first U.S. network special titled, "One Direction: The TV Special." The event will air on NBC on Dec. 23 and "will offer a rare inside look at the wildly popular band through a combination of documentary material, comical stunts and musical performances."

According to E! Online, the show will also include behind-the-scenes clips from the South American leg of their "Where We Are" tour as well as footage from the group finishing up their album "Four."
