Hosted by Kelly Clarkson, the dazzling display of musical talents, star-studded surprises and the lighting of the world’s most famous Christmas tree remains one of the holiday season’s most anticipated events. Audiences will be treated to festive performances from an all-star lineup of musical guests featuring Backstreet Boys, Dan + Shay, Megan Hilty, Jennifer Hudson, Coco Jones, Little Big Town, RAYE and Thalia. In line with tradition, the Radio City Rockettes, stars of the annual Christmas Spectacular at Radio City Music Hall, will wow viewers with a festive performance. NBC’s “TODAY” anchors Savannah Guthrie, Hoda Kotb, Al Roker and Craig Melvin will once again join the tree lighting for a special appearance.
