April 2 (UPI) -- Miranda Lambert and Anderson East dazzled on the red carpet Sunday.
The 33-year-old country star and 28-year-old singer attended the 2017 Academy of Country Music Awards in Las Vegas, where Lambert won Female Vocalist of the Year.
The "Vice" singer turned heads in a white gown with a shimmering floral pattern and 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 performed her new song "Tin Man" at the awards show. The track appears on her sixth studio album, The Weight of These Wings, which won Album of the Year at the ceremony.
"[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."
Lambert was also nominated for Single Record of the Year, Song of the Year and Video of the Year for "Vice," but lost to Florida Georgia Line, Thomas Rhett and Joseph Kahn, respectively. 2017 marks her eighth consecutive Female Vocalist of the Year award win.
