The singer -- who debuted her baby bump ahead of Wednesday's ACM Awards -- took the stage in Nashville to perform her latest song, a heartfelt tribute to the innocence of childhood and a call to action about racism, sexism, abuse and more.
"What are you gonna tell her / when she figures out / that all this time you built her up / just so the world could let her down?" Guyton croons in the chorus of the song, addressing the parent of a child who is growing up thinking "life is fair, and God hears every prayer, and everyone gets their ever after."
Urban accompanied Guyton during her performance, playing the piano. The singer concluded her performance by sweetly cradling her baby bump.
The country star spoke with ET ahead of her performance, opening up about what she was hoping to bring to the stage as a Black woman in an industry and awards show space that is still overwhelming dominated by white men.
"There's not a single woman that I know that hasn't gone through something, and I just hope that this song and people hearing me sing it inspires change," she said. "I hope this song gives everybody that fire within them to change to help make change for our future."
"Starting my career off, I never thought of myself as some activist," Guyton admitted. "I was actually always someone that kind of just stayed in the back and didn't want to make any noise or rock the boat -- and then everything kind of shifted for me. To step in that role as a woman, as a black woman, it is such an honor that people are giving me this opportunity to be heard and to hopefully incite change. It means the world to me."
Academy of Country Music CEO Damon Whiteside also spoke to ET about Guyton's performance, saying that it was going to a highlight of the night for him -- particularly during the atmosphere of unrest and ongoing protests about racial injustice and police violence across the country.
"[We] certainly also want to show some of the great African American artists that we have, and [who] have had a lot of success in our industry this past year," he said. "America is going to discover Mickey Guyton that night, if they don't know her, and she is going to blow everybody away with her voice and her talent and songwriting abilities. And I am just so excited to see that, and I think it's going to be one of the most talked-about moments in the show that night."
