It's official: Brooks and Dunn are back and they're headed for Sin City! And oh, by the way, they're bringing Reba along for the ride.

On Wednesday, it was announced that the three country powerhouses will be newest headliners to get a Las Vegas show. Signing at 2-year deal, Reba along with Brooks and Dunn will play inside The Colosseum at Caesars Palace beginning in June 2015.

"It's gonna end up being the perfect storm," Ronnie Dunn said, "total chaos, which is where I live."

The country duo famously split following a 2010 "farewell tour" after 20 years together. Both have done well since the split -- Ronnie Dunn had a No. 1 album and Kix Brooks hosts the successful American Country Countdown -- but it's fair to say that neither has captured the magic that Brooks and Dunn had as a twosome.

Ronnie Dunn recently hinted at a reunion on Facebook, saying, "…. talking to Kix. He's talkin' back."

The reunion is surprising to some, considering rumors of discord and full-blown hate have centered around Brooks and Dunn for years. The duo has laughed off the rumors, as has Reba, claiming she didn't even have to play "matchmaker" to get them back together.

"I don't think there was a matchmaker," she said. "When Kix said yes and Ronnie said yes, I was so happy. I like being on stage with them. The hijinks are unnameable."

Playing off the notion that the chart-topping duo can't get along, Kix said, "We needed a good referee. She kind of makes us both behave. It really is a great way for Ronnie and I to get back together. I think it's been a great break for both us. People ask, 'Why did you break up?' And I'm like, dang, we were together for 20 years.' I was proud of us. We made a lot of good music. We got to the point where it was fun to do some other things. Those songs are still a big part of our lives."
