Since her breakthrough on American Idol in 2005, Carrie Underwood has continued to captivate fans with her powerful voice and original songs. In 2020, she decided to spread some holiday cheer with her Christmas album My Gift, filled mostly with beloved classic holiday tunes. The album features a special duet with John Legend—but one track shines even brighter, starring someone even closer to Carrie’s heart: her son, Isaiah Fisher.

For the timeless song Little Drummer Boy, Carrie invited young Isaiah, who was around 6 years old at the time, to join her. His sweet, innocent voice fits the song perfectly, adding a warmth that only a child’s voice can bring.

Carrie shared her excitement in a behind-the-scenes video: “Little Drummer Boy is one of my favorite Christmas songs, and I wanted to make it extra special this year. So I asked my very special duet partner to join me.”

Like his mom, Isaiah loves singing and spreading joy through music. Their duet is not just a performance—it’s a memory Carrie treasures forever. “If nothing else,” she says, “I’ll have this for the rest of my life. It’s the perfect piece of the puzzle for this album.”
