Blake Shelton's wife was up against Sheryl Crow, Kacey Musgraves, Taylor Swift as well as Carrie Underwood and she praised some of them in her acceptance speech.

"I can't believe this. I really didn't expect it y'all. Thank you so much," she said. "I was just hanging out with Trisha Yearwood and I was standing next to Sheryl Crow, complete and utter rock star. And Kacey Musgraves, I grew up with her. She wrote the single of the year this year. Carrie Underwood is my buddy and she's a phenomenon."
