Carrie Underwood is the reigning ACM Entertainer of the Year winner, which she shared with Thomas Rhett in 2020

Carrie Underwood took us to church at the 2021 ACM Awards.

On Sunday, the singer, 38, performed a medley of gospel hymns off her latest album My Savior. Underwood started her performance with a stunning acapella rendition of "Amazing Grace."

The American Idol alum — who wore a sparkly beige gown — then transitioned into "Great Is Thy Faithfulness," before being joined by CeCe Winans.

"Ladies and gentlemen, the legendary CeCe Winans," Underwood said, welcoming her to the stage as the two belted the hymn. The two then sang "The Old Rugged Cross" before Underwood, backed by a choir, closed her performance with a show-stopping rendition of "How Great Thou Art Are."

Underwood's performance — which was presented by Dolly Parton — ended with a standing ovation from the audience.

The last time the pair sang the church classic together was earlier this month as part of My Savior: Live From the Ryman, Underwood's Easter livestream event.
