Miranda Lambert and Anderson East dazzled on the red carpet on Sunday.
The "Vice" singer turned heads in a white gown with a shimmering floral pattern and a plunging neckline, while East looked dapper in a blue suit.
The couple confirmed their relationship in 2015 following Lambert's divorce from Blake Shelton.
Lambert will perform her new song "Tin Man" at the awards show.
The track appears on her sixth studio album, The Weight of These Wings, which was released in November and is nominated for Album of the Year."[It] feels like my diary got nominated," the star said of the album in a recent interview with the Tennessean. "[The nomination] is a huge thing, especially for this one."
"I feel like I covered every emotion on this record that you can cover because I had 24 songs to do so," she added of the two-disc album. "I felt like it went with my moods."
2017 would mark her eighth consecutive Female Vocalist of the Year win.
