Carrie Underwood had fans in tears this week when she performed a stunning rendition of "O Holy Night" on The Tonight Show Starring Jimmy Fallon. The country star chatted with the host via video link on December 3 and shared a pre-recorded version of the hymn which had viewers sharing their praise.

The performance, which can be seen via the YouTube video below, was stripped back and let the multiple Grammy winner's powerhouse vocals shine through.

She kept things simple with a scaled-back live band, featuring violins and a piano. The "Cry Pretty" hitmaker performed with understated Christmas trees behind her as she stood in front of a large screen depicting a starry scene with one extra large star in the top left corner.

Carrie wowed in a satin navy blue gown, which finished below the knee and was fitted around her middle to highlight her slim waist. It had a high neck and billowing sleeves which gave a glimpse of her toned lower arms.

The mom of two wore her signature blond hair down in curls cascading over her left shoulder, and she held a seriously high note with ease at the end of the song as snow began to fall behind her.

Viewers were floored by her vocals, with some admitting that the powerful rendition left them crying.

"I didn't think I would be sobbing at 20 past 5 this morning but omg @carrieunderwood singing o holy night was beautiful," another user wrote on Twitter.

"Wow! Carrie Underwood singing Oh, Holy Night on the Tonight Show. Amazing!" a third tweet read.

"Wonderful voice and a touching performance #FallonTonight," a fourth viewer tweeted with several clapping hand emoji, two red hearts, and a four-leaf clover.

The song is featured on Carrie's first Christmas album, My Gift, which she promoted on the show.

Carrie's been gifting fans with a host of treats this week. Her gorgeous performance came the same day as she dropped a new duet in which she sings in Spanish.

The musical stunner teamed up with David Bisbal for the upbeat Spanglish Latin pop track "Tears of Gold," and the duo released the music video for the song on the morning of December 3.

In it, Carrie wowed in a mini dress which revealed her world-famous legs as the two sang while gold confetti fell around them.
