Justin Bieber will be joined by Mary J. Blige, Christina Perri and more for the 13th annual Home For the Holidays With Martina McBride special. The special will air on Dec. 21 at 8PM ET and run for an hour, per McBride's website.

The moving holiday special will feature tales of adoption from foster care. Also on board are McBride herself (obviously), OneRepublic and Gavin DeGraw. Talk about star-studded and for a good cause! All the aforementioned artists will perform. Additionally, Actresses Katherine Heigl and Denise Richards, both of whom have adopted daughters, will be on hand among the performers.

Following the success of the past 12 annual shows, the special continues to tell touching stories about adoption from foster care in hopes of raising awareness for this important social issue. The inspirational stories of American families are enhanced with performances by some of today's most popular artists!

Heart-warming, feel-good tales of adoption mixed with tunes from The Biebs and Mary J? We couldn't think of a better way to spend an hour parked in front of the TV four days before Christmas. It's a perfect blend of the spirit of the holidays and pop music.
