YouTube Red has ordered The Keys Of Christmas, an original holiday musical variety special starring Mariah Carey and YouTube comedy star Rudy Mancuso that will feature original musical performances by the likes of Ciara, DJ Khaled and Fifth Harmony along with YouTube's top music personalities. Endemol Shine North Ameriaca and its digital studio Endemol Shine Beyond USA and Just Entertainment Studios are producing, with a December 19 debut date set.

The ensemble cast will shepherd Mancuso, who has more than 1 million subscribers on his YouTube channel, on a magical adventure of the true meaning of Christmas, and shows what happens when you accidentally go off the grid on Christmas Eve with no phone and no way to function. Music video helmer Dave Meyers (Katy Perry's "Firework," Pink's "Just Like Fire" and Rihanna's "Where Have You Been") will direct.

Original music will come from the the likes of Alex Aiono, Boyce Avenue, Nicky Jam, Bebe Rexha and Gregory Brothers. Mike Tyson will also make a guest appearance.

"Music is wildly popular on YouTube and we're excited to bring together some of the biggest names in music alongside some of the biggest stars on YouTube," said Ben Relles, Head of Unscripted at YouTube Originals. "The musical icons and rising artists in The Keys Of Christmas bring this new holiday tale to life. We are also thrilled to have YouTube comedy star Rudy Mancuso in his first leading role in a music special."

YouTube Red is a paid membership that includes exclusive access to new original series and movies from top YouTube creators.

"The Keys Of Christmas is truly a modern take on the holiday variety special, bringing together traditional and digital natives in this very unique musical format for the YouTube audience," said Bonnie Pan, President, Endemol Shine Beyond USA. "Dave Meyers, who has an amazing track record working with the top musical acts of our time, had a vision and was able to weave that into a fresh new format with the likes of Mariah Carey, Ciara, DJ Khaled, Fifth Harmony, Rudy Mancuso and many other incredible performers just in time for Christmas."
