ET spoke to Rhett at the ACMs Monday where he shared the reason he had to stand so still on the carpet.
ET's Cassie DiLaura spoke to the country music artist ahead of the show, where he revealed the wardrobe malfunction he had that him asking us to keep our cameras strictly above the waist.
"My zipper fell off right before, so I'm taped up," Rhett revealed. "So, I'm trying to stand really still right now, so make sure the camera's just like right here."
Rhett, who was up for Male Artist of the Year and Album of the Year, and performed twice at the awards show, had plenty of outfits to change into. While the show started with a fashion flub, the "Angels" singer told ET he's just "blessed to be here."
"It is a big night," he gushed. "I mean, first time we've done this with real people in a while, and I got out of the car right before Dolly. I was like, 'this is amazing,' but yeah, getting to perform two songs, nominated twice, just very, very blessed to be here."
Rhett, who usually has his wife, Lauren Akins, by his side, was riding solo tonight.
"Our kids are still sick, and she couldn't make it out," Rhett shard. "It's killing her not to be here."
While Akins couldn't be with him at the 57th annual awards show, she will be joining the celebrated singer for his birthday celebration later this month.
"We are going to Telluride, Colorado," he said of his birthday plans. "It's like one of our favorite places to go, and mom and dad haven't had a just us two trip in a minute, so, we're looking forward to it."
The father of four, who shares, Willa Gray, 6, Ada James, 4, Lennon Love, 2 and Lillie Carolina, 3 months, with Akins, will be celebrating with the little ones too, adding that the day of will likely be a "chill day with the kids."
"I'll be 32, which is crazy to me, probably just a chill day with the kids," Rhett went on to say. "They will probably make me a sweet little birthday card or something like that."
