The upcoming 'Christmas in Rockefeller Center' TV special just got a little more star power. Darius Rucker has been added to the lineup, which also includes fellow country stars Trisha Yearwood and LeAnn Rimes.

The annual show celebrates the lighting of the Christmas tree in New York City's Rockefeller Center. This year's tree, an 85-foot Norway Spruce from Hemlock Township, Pa., is approximately 90 years old and weighs about 13 tons.

The country singers will be joined by Lady Gaga and Tony Bennett, Cyndi Lauper, Seth MacFarlane and Sara Bareilles, Idina Menzel and Pentatonix, as well as ‘Today’ show anchors Matt Lauer, Savannah Guthrie and Natalie Morales.

Rucker's appearance at 'Christmas in Rockefeller Center' is not the only way he is ushering in the holiday season. The singer-songwriter recently released his first Christmas album, 'Home for the Holidays,' which includes guest vocals by Sheryl Crow on 'Baby, It's Cold Outside.'

“This has been a lifelong dream," the South Carolina native says of the record. "I hope my fans enjoy listening as much as I enjoyed making it.”

‘Christmas in Rockefeller Center’ will air live on Wednesday, Dec. 3, at 8 PM ET on NBC.
