In her CMA Country Christmas debut, Carrie Underwood took the stage with legendary Christian recording artist Michael W. Smith for a beautiful performance of 'All Is Well,' off Smith's Christmas record 'The Spirit of Christmas.'

The set behind the two singers made it appear that they were in an intricately decorated, light-filled cathedral, and Underwood stunned in a floor-length navy blue gown, her baby bump keeping her company as she belted out the song. Next to her, Smith played the piano and added his vocals, turning the duet into an absolutely spell-binding piece.

Underwood undoubtedly has one of the best, most powerful voices in music, and her abilities were put on worthy display in 'All Is Well.' She soared in her CMA Country Christmas debut, giving fans a beautiful gift in the form of song.

Smith also performed 'Silent Night' with country quartet Little Big Town during the event.
