Fifth Harmony, Mariah Carey & More Star in YouTube's 'The Keys of Christmas': Watch the Trailer

YouTube Red is getting into the seasonal spirit with The Keys of Christmas, the network's first original holiday special. The newly released trailer teases performances from famous friends Mariah Carey, Fifth Harmony, DJ Khaled, Bebe Rexha and Ciara.

The special's title is of course a nod to one of DJ Khaled's many taglines, and the producer plays a guardian angel who imparts his wisdom unto YouTube musician Rudy Mancuso. "Rudy's not a bad guy. He just don't see the big picture," Khaled says about the Scrooge-like Mancuso. "He doesn't hear the beat. He doesn't have the keys of holiday spirit so we're going to give the keys to Rudy."
