Blake Shelton and Gwen Stefani first began their romance acting as judges on the hit reality show The Voice, so it's only fitting they would perform their latest duet on the famous stage.
Watch Shelton and Stefani's adorable performance in the video below:
While working on their holiday project, Shelton shared with People how Stefani had called him while he was on the road to tell him all about her idea for a Christmas song. "She was so excited,“ he said. "I love seeing her that happy. She's so happy when she's writing and just hearing that in her voice and how into it she was, I just couldn't stop thinking about it so I got my guitar out and thought, 'I wonder if I could help her in some way?'"
The country sensation added, “I couldn't have been more honored or more proud to be on one of her records."
The duo's duet is available on iTunes and streaming services now.
