After arriving to L.A.’s Microsoft Theater in a floor-length, bump-hugging black gown, the expectant singer changed into a flowing maroon dress to take the stage. Onstage, Underwood stood atop a rotating circle surrounded by lit candlesticks and a backing string group for her emotional performance, which garnered a standing ovation from the star-studded crowd, including Camila Cabello.
On the red carpet pre-show, opened up about the substance abuse-inspired song.
“I feel like when we wrote this song ‘Spinning Bottles’ we kind of each had people in our heads go through this,” she said of the track. “It’s hard to write, it’s hard to get it out, it’s hard to say it’s gonna go on the album … It’s difficult to sing it to the world, but its life; that’s a part of life. It’s hard to just put yourself out there like that.”
Underwood added: “Your’e just going into a writing session letting your feelings out and just hope people get it.”
“Such a wonderful night! I am honored and humbled by the love I received from you all tonight. I made absolutely no sense in my speech and didn’t say half of what I should’ve, but I want you all to know that your support means everything to me!” she wrote on Instagram following the show.
“Also, I am beyond honored to be in the company of such talented ladies like @marenmorris and @kelseaballerini to represent the women of Country Music tonight. That said, I’m off to peel this dress off and cuddle up to my little man! I shall go to bed with a full and happy heart! ❤️💖❤️💖❤️ And, of course, thank you #AMAs for having me and for letting the fans call the shots!”
