Kelly Clarkson freely admits she's a complete Christmas junkie, going so far as to feature a recurring segment called "Ambush Christmas" on her syndicated daytime talk show. The Grammy- and Emmy-winning music superstar celebrates the release of her 2021 holiday album with this festive special featuring new original songs as well as iconic yuletide classics, plus dancing and collaborations with special guests. Among those appearing are Ariana Grande, Brett Eldredge, Melissa McCarthy, Leslie Odom Jr., Jay Leno and Amy Poehler, plus a certain beloved North Pole personality.
