Watch Danielle Bradbery's Stunning 'O Holy Night' Performance (Exclusive)

Danielle Bradbery is getting in the Christmas spirit.

The 21-year-old "Sway" singer stopped by ET's Certified Country set to deliver a stunning, stripped-down rendition of the holiday classic, "O Holy Night."

"I always grew up listening to it and I love hearing all the versions," she says, citing Carrie Underwood's take as one of her favorites. "It's just such a beautiful song."

Bradbery will head home to Houston, Texas, to spend the holiday with her family -- a sweet ending to a huge year for the singer. Four years after winning The Voice and dropping her self-titled debut in 2013, Bradbery released her sophomore album, I Don't Believe We've Met, earlier this month.

"I have been just nonstop, but it's the greatest busy that you could be," she says. "It's been pretty exciting."

While her new LP makes a great stocking stuffer for 2017, Bradbery is open to curating her own collection of holiday tunes in the future.

"When the time is right, obviously, I would love to do a Christmas album," she says. "I love Christmas, it's just so happy!"
