"We sing together, we have costume changes," she reveals of the performance. "I didn't want it to be me 30 minutes, them 30 minutes. I want to sing with them. I want them singing with me. It's just a lot more fun. I wanted to have fun singing with them." 03 of 12 GREEN ROOM GANG Dustin Haney Brooks and Dunn hang with Kix's son Eric and Ronnie's daughter Haley backstage. "At this point in our career to have some consistency, it really takes a load off," Brooks tells PEOPLE. 04 of 12 GOOD GREET Justin McIntosh Of having their faces plastered all over the Vegas strip, McEntire says, "I love it.

You know that you're doing something right and people are interested." 05 of 12 FAMILY AFFAIR Justin McIntosh The singer poses with her husband, Narvel Blackstock (left) and son Shelby. "It's a billion times better than anything I could have thought of," she says of the show. "It's really that good." 06 of 12 STORY TELLERS Dustin Haney "There was never a rift," Dunn, pictured with Brooks and manager Clarence Spalding, says of rumors he and Brooks were at odds when they split in 2009. "We did it because we'd been doing it for over 20 years and felt like we'd accomplished everything that we could. We're getting to a point where we were comfortable enough to hang out at home for a while and I think the best way to go about that was compromise. We'd been going all of the time." 07 of 12 GOING GLAM Justin McIntosh Decked out in her fringed top and knee-high boots, McEntire gets one last touch-up from hair and makeup stylist Brett Freedman. 08 of 12 LETTER PERFECT Justin McIntosh Flowers and light-up letters adorn McEntire's dressing room.

We had a blast and we're tightening up a little bit." 10 of 12 STAGE RIGHT Dustin Haney "We ran out of gas," Brooks says of Brooks amp Dunn's disappearance from the spotlight. But with the opportunity to do a Vegas residency, "[we] thought, gosh, if we can come out here and golf and eat some great dinners in one of the greatest venues in the world, then yeah … and we got our favorite referee." (Reba, of course!) 11 of 12 BIRD'S-EYE VIEW Dustin Haney "It's nice to have the support," Brooks says of the stars' fans. "We've all done shows where you don't see marketing and most of these shows looks like they're going to sell out. The fact that they are still out there supporting us, they're obviously proud that we're here and we're proud to be here." 12 of 12 READY FOR ANYTHING Dustin Haney "For the next three weeks we need to be on our games," Brooks says. "There are people coming in for this. We gotta give it to them."
