Carrie Underwood is giving fans a behind the scenes look at recording "Little Drummer Boy" with her five-year-old son, Isaiah, from her new Christmas album, My Gift.
On Tuesday (December 1), the country star turned to Instagram to share an adorable snapshot of her and Isaiah recording the track together in the studio. "So happy we captured the sweetest voice in this special moment in time," Underwood wrote alongside the photo.
"My own Little Drummer Boy will be a part of the #MyGift Christmas Special beginning this Thursday on @hbomax," she added.
"It was so great," the singer told People of the duet with her son. "When we recorded, I was able to be in the booth with him and encourage him and try to remind him what words were coming up next, things like that."
Underwood went on to reveal how touching it was for her to hear Isaiah's part after the studio session. "I got to listen to his vocals [get] put together and then listening to myself with him," she explained. "I was laughing, and I was crying, and it was just very overwhelming in a good way. It's just very emotional."
Underwood's upcoming HBO Max holiday special, My Gift: A Christmas Special From Carrie Underwood, will include performances of traditional Christmas classics, along with some new tracks from My Gift.
