The Masked Singer

FOX | 8:00 pm

The mood on this wacky music competition series is even more festive than usual in this two-hour special holiday episode, which highlights several never-before-seen seasonal performances from fan-favorite contestants. Hosted by Nick Cannon — with judges Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke along for the (sleigh) ride — the special includes season's greetings from celebrities in the "Masked" family, some amusing bloopers and other previously unseen behind-the-scenes footage. Also: a rendition of "Rudolph the Red-Nosed Reindeer" that no fan will want to miss.
