The two performed their hit “Drunk (And I Don’t Wanna Go Home)” while donning leather jackets decorated with long pink and blue tassels.
The show is taking place at several locations across Nashville, Tenn., including the Grand Ole Opry House, Ryman Auditorium and the Bluebird Café.
Next came a performance of “Famous Friends” by Chris Young and Kane Brown.
After bouncing back from a dangerous accident, country newcomer Blanco Brown presented the first award of the evening for group of the year, which went to Old Dominion. In their speech, the group expressed pride in being nominated alongside “such bada—-.”
Meanwhile, Thomas Rhett sang a medley of tunes including “What’s Your Country Song.” Lambert then took the stage once more — this time at the Bluebird Café — to sing with Chris Stapleton after the star’s wife had to skip out on the performance reportedly due to a “prior doula commitment.”
Dierks Bentley was also memorable onstage, singing U2’s “Pride (In the Name of Love)” with The War and Treaty, the extremely talented husband-and-wife duo.
Collaborative moments were a theme during the awards show.
Another duet was Ryan Hurd and Maren Morris. The couple sang “Chasing After You,” and sweetly shared a kiss after.
Carrie Underwood wowed viewers, singing a medley of faith songs. Underwood was introduced virtually by Dolly Parton, who noted that the pair shared their faith.
Underwood, who dazzled on-stage, was then joined by CeCe Winans for a powerful duet.
Underwood performed songs from her recent gospel hymns album “My Savior,” and she and Winans blended their voices like angels onstage. Underwood kicked off the performance with “Amazing Grace” and “Great Is Thy Faithfulness,” then Winans joined in, matching her strong vocal performance.
Host Urban also rocked the stage with a performance of “Tumbleweed.”
But not everything went smoothly. The Grammy-winning duo Dan + Shay performed their latest hit, “Glad You Exist,” but the pre-taped moment aired out of sync.
“Apparently there was an audio/video sync issue on the television broadcast,” the duo tweeted. “We’re bummed about it, but it happens, especially when performances are happening in multiple locations.”
Another mishap occurred when Martina McBride announced the winner of single of the year. McBride correctly said “I Hope You’re Happy Now” by Carly Pearce and Lee Brice won, though “I Hope” by Gabby Barrett appeared on the TV screen.
As far as top nominees, Stapleton and Morris led with six nods each. Stapleton’s nominations include album, song and male artist of the year. Morris’ nominations include single and female artist of the year. She also landed a group of the year nod as a member of the Highwomen, the supergroup also featuring Brandi Carlile, Amanda Shires and Natalie Hemby.
As Morris accepted the song of the year award for her Grammy-nominated hit “The Bones,” which topped the country music charts for months last year, the star got teary-eyed.
“When I wrote (‘The Bones’) I was dating my now-husband and it was just a song to him. And I feel sometimes, like, songs know you better than you know them at the time. And I feel like this song has revealed so many new things to me,” she said. “And this is just been a hell of a year and hopefully country music and maybe even this song brought you and your family and friends some peace.”
Some of the ACM winners were pre-announced, including Gabby Barrett (new female artist), Jimmie Allen (new male artist) and Kane Brown (video of the year). Carly Pearce and Lee Brice’s platinum hit “I Hope You’re Happy Now,” co-written by Luke Combs, won music event of the year.
