Lambert wowed in a nude Swarovski crystal-covered Randi Rahm gown with her wavy blonde hair cascading down her shoulders. Her adoring husband of almost three years wore cowboy boots, jeans, and a black vest and jacket.
The "Boys Round Here" crooner co-hosted the evening's ceremony with pal Luke Bryan, and both he and his wife were up for numerous honors including the coveted Entertainer of the Year title.
After her husband had to leave her side for his hosting duties, Lambert posed with friends Carrie Underwood, Taylor Swift, Keith Urban, and Voice contestant RaeLynn.
Earlier in the evening, Shelton and Bryan posted a goofy selfie for fans, tweeting, "I think @LukeBryanOnline and I are either ready or high."
