Chris Stapleton and H.E.R. Perform 'This Christmas' at The National Christmas Tree Lighting

Chris Stapleton and H.E.R. prove once again that two is better than one. They beautifully blended their vocals to perform "This Christmas'' during the National Christmas Tree Lighting. On Dec. 2, LL Cool J hosted the 99th annual ceremony in Washington D.C. The event first took place in 1923 and was broadcast nationwide on Sunday, Dec. 5.

President Joe Biden and First Lady Jill Biden helped light the tree, paying tribute to service workers and the U.S. military. Vice President Kamala Harris and husband Doug Emhoff also attended the ceremony.

By far one of the most unforgettable moments of the night was by the Grammy Award winners, performing Donna Hathaway's 1970s' Christmas song. The R&B singer traded in her signature guitar for a piano, while Stapleton played an electric guitar for their performance alongside the U.S Army Band Downrange.

The duo was surrounded by festive lights and decorations as the audience watched in awe. Other performers of the night included Kristin Chenoweth, Maren Morris, Billy Porter, Patti LaBelle and more.
