"Hallelujah" appears on Underwood's latest album, My Gift, which marks her first full-length holiday project. The set was produced by Greg Wells and includes eight traditional and three original songs.
Released on Sept. 25, My Gift recently earned Underwood her eighth total and consecutive No. 1 on Billboard's Top Country Albums chart.
"It has been in my heart to do a Christmas album for years, and we started planning this last year when we finished the Cry Pretty Tour 360," Underwood tells Billboard. "Who would have known what would happen in the world since then, and how much we would all be ready for the hope and joy that Christmas music embodies this year more than ever."
Legend will also appear on Underwood’s upcoming music special My Gift: A Christmas Special From Carrie Underwood, which will be available for streaming through HBO Max on Dec. 3.
