Hunter Hayes and Darius Rucker will help celebrate the holidays as part of a star-studded TV special, 'Christmas in Washington.'

The country music singers are part of an eclectic cast, which includes Aloe Blacc, Rita Ora and Christina Perri, as well as movie and WWE star Dwayne 'The Rock' Johnson, who will host the event.

'Christmas in Washington,' now in its 33rd year, will be attended by President Barack Obama and First Lady Michelle Obama, along with several other dignitaries from our nation's capital. It will be taped at the National Building Museum on Dec. 14 and premiere on TNT on Dec. 19 at 8 PM ET.

Rucker's appearance on the TV special is only part of the way he is helping his fans celebrate the festive season. The South Carolina native released his first Christmas album, 'Home for the Holidays,' in October, which includes a duet of 'Baby, It's Cold Outside' with Sheryl Crow. Rucker also performed as part of the all-star 'Christmas in Rockefeller Center' on Dec. 3 in New York City.
