"It's just amazing.You know, winning Song of the Year was pretty spectacular, because 'Die a Happy Man's' first win ever was last year at this same awards show for Single of the Year. So, I feel like this song has given me a year's worth of benefits," Rhett shared. "And then Male Vocalists, still don't have really much to say about. That is the most surreal award I've ever been given."

"My heart is actually still racing from being up there," he added. "Just being surrounded by that much talent [was amazing]. I've toured with all these people. And people like Chris Stappleton, man... what an undeniable voice and talent. I'm just so grateful for this award, 'cause that's the coolest thing that's ever happened to me."

Next for Rhett is album No. 3, which he said will be out later this year.

"We finished it in January," he revealed. "[I] just got to perform with Maren [Morris] the first single off the record, called 'Craving You.'"

"It's all over the place," he said of what fans can expect. "That's just what I do, which is, when I hear songs I like, and hear things I like about certain songs, I love to just kind of take things and make them my own. And we went in the studio and cut, like, 22 songs, which is way too many."

For now, though, Rhett is focusing on his big wins -- which he said his pregnant wife, Lauren, is ready to celebrate.

"I don't know [what I'm going to do]. I'm gonna go to some parties, say hey to some friends, play some blackjack. Last year, me and Brett Eldridge stayed up until 6 a.m. in the morning. Didn't go to bed, went straight to the airpot. Not doing that again," he confessed. "My wife's been killin' it out here. She's been a party animal."

"For being 22 weeks pregnant, that girl is ready to party," Rhett said. "She is the best craps player. If you get the chance to sit at a table with Lauren, you will sit there for an hour while she rolls dice. It's amazing. It really is."
