Pentatonix returns to NBC on Dec. 10 for another holiday special.

Pentatonix: A Not So Silent Night will be the three-time Grammy-winning group's third special for the network. The group has become a staple on the network's specials that celebrate the lighting of the Rockefeller Christmas tree. 

Pentatonix likes the glitz and glamour; this new special takes them through neon-lit Las Vegas.

Fellow North Texas stars Kelly Clarkson and Maren Morris, who guest-star on the group's fourth holiday album, will also appear on the special. (Pentatonix also opened for Clarkson on one of her tours.) Other guests include the Backstreet Boys, who have a residency in Vegas, and Penn & Teller.

Pentatonix is currently on tour to support that album, Christmas Is Here. The tour kicked off Nov. 25 in Grand Prairie at The Theatre.

The special will air Dec. 10 at 9 p.m. on NBC.
