Carrie Underwood Singing Blake Shelton Is Not What We Expected

Carrie Underwood joined The Voice coach John Legend to sing a Blake Shelton song that even the country singer needed to applaud.

Prior to the season finale of The Voice on NBC, Carrie Underwood joined John Legend for a promo interview and a performance of Shelton’s early hit “Austin.”

Look for Underwood and Legend to sing “Hallelujah” during the finale on Tuesday night (Dec. 13).

“Let the world stand still, the church bells ring / Silent night as the angels sing / Hallelujah, Hallelujah / Let the magic warm the moonlit air / Hear the choirs join in singing everywhere / Hallelujah, Hallelujah,” they sang in unison, bringing the Christmas magic to life in the Universal Studios room in Hollywood, Calif.
