Miranda Lambert admits that when she opened her first Las Vegas residency at Planet Hollywood’s Zappos theatre last weekend (9/23), she had butterflies in her stomach, but the show went great.

Miranda told Extra TV after the show, “Yeah, I feel like I was nervous at first, but when I finally got on the stage, and there were people in the house. We’ve been rehearsing into an empty room. It just felt like my normal day at work, but taken up a bunch of notches.” She continued, “I settled into, like, ‘I’m just doing a show. That’s what I do.’ I was psyching myself up a little bit, but it was a great night!”

Lambert also explained what fans could expect from her big debut in Sin City, which she had planned for months. She described the show as “A honky-tonk on steroids. That’s what it feels like to me. But I know this is Vegas, and so you got to bring it, and so I feel like we just took everything. I love this cowgirl, rock ‘n’ roll, honky-tonk vibe — and just blew it up. I think the wardrobe part was actually inspired by the Cowgirl Hall of Fame. I was inducted [into] the Cowgirl Hall of Fame back in October, and I had sent my stylist video of all the costumes and jumpsuits and outfits worn by some of the most famous cowgirls.”

Her husband, Brendan McLoughlin, was there to cheer her on opening night, and so were a couple of her close friends. Miranda gushed, “It was awesome. Ashley Monroe was here. My fellow Pistol Annie. And my best friend from second grade, Lacey, was here. And we, actually, tonight is our 20th high school reunion… So it was really cool to have, like, two of my oldest girlfriends.”

She added, “It felt good to have that support because they’re ‘home’ to me, you know? But I have a lot of guests… pretty much every night, which is fun, but I was just glad to just get my show on the road.”

Lambert also told Extra that her husband Brendan is more than ready for the Vegas lifestyle. She explained, “My husband’s very happy about all the amazing chefs that have restaurants here. And we’re very, like, outdoorsy, so there’s so much to do. That’s outside of the strip. That’s beautiful. And I love the desert. I love the mountains. So I’m looking forward to spending time like just learning the terrain and, you know, exploring.”

Miranda posted to Instagram yesterday (9/28) along with several images from the show, “I’m so happy to have the Velvet Rodeo Residency up and running. Thanks to everyone who came to see us on opening weekend! Hope y’all are ready for wild Wednesday. It’s show 3 time!”
