Instead of packing her bags, heading to the airport and making her way home to her family after living life on the road for a bit, Carrie Underwood decided to wrap her latest trek with an epic send-off: she and her band went straight to Las Vegas to catch a Guns N’ Roses show together after their last night of tour.

On The Tonight Show Starring Jimmy Fallon on Friday (March 6), Underwood stopped by to talk about her new health and fitness book Find Your Path: Honor Your Body, Fuel Your Soul, and Get Strong with the Fit52 Life. She also talked about the evening she’s since dubbed “the best night of my life” at this year’s Country Radio Seminar, which involved her effectively prolonging her trip home to her husband and sons so she could go see one of her favorite bands for the very first time.

“We were nowhere near Las Vegas, so naturally I said, ‘Let’s go to Las Vegas with the band and go see GNR play!'” she told Fallon. “It’s kind of a life-long dream of mine I never thought would happen. Couldn’t waste that opportunity, so I abandoned my husband, abandoned my children, went to Vegas, and saw Guns N’ Roses. AMAZING.”

Instead of going with her typical VIP treatment with luxury box seats, Underwood and Co. opted to get down in the crowd with everyone else — and it was perfect.

“Usually, when I go to concerts, I’m like, in a box on the side, which is great — it has it’s perks, there’s usually a bathroom in there, it’s kind of awesome,” she said. “But you miss the energy of the crowd. Because we were in Vegas, we were just in there with everyone else, it was absolutely incredible. You could feel everybody, everybody was screamin’, I was screamin’ — I was like, ‘I’m never gonna see none of these people ever again, I’m gonna act like a fool!’ — it was amazing.”

Underwood’s devotion to Guns N’ Roses is familiar to longtime fans, who have seen her cover their songs and heard her gush about her hopes for a collaboration for years. She finally got to meet the GNR frontman in Vegas, and the experience was everything she hoped it would be.

“I might have, like, hung out with Axl after the show a little bit!” she joked. “I do always say that it’s hard when you meet your heroes, because I do consider him to be somebody who taught me how to sing, because I loved how he could just do different things with his voice. I was like, ‘I don’t know! If I meet him, and he’s not everything I want him to be –‘ But he was. It was . great. He was super cool, and nice, and we talked — we’re best friends.”
