Kix Brooks and Ronnie Dunn, known as the country duo Brooks & Dunn, made a major news on Wednesday, December 3. They are teaming up again after performing their final Last Rodeo concert together at Nashville's Bridgestone Arena in September 2010.

Brooks & Dunn had made a career in the country music industry for 20 years when they called it quit four years ago. Each of them pursued solo careers but never lost touch with each other. Dunn recently hinted about the reunion on Facebook, saying he had been talking to Brooks lately.

And then it was announced that they would be sharing the stage again at the Colosseum at Caesars Palace as Reba McEntire's co-headliners. McEntire will have her 12-day residency at the Sin City venue following Celine Dion's departure. The first three dates will be June 24-27, 2015. Additional shows are scheduled for the weeks of July 1, December 2 and December 9.

Tickets for "Reba, Brooks & Dunn: Together in Vegas" will go on sale Thursday at 10 A.M. PT at the Colosseum at Caesars Palace Box Office. Another major headliner will be announced in January.

There is no word yet whether the reunion will extend to a new joint album. They have released solo albums following their split and continued a career in different paths. Brooks is hosting American Country Countdown radio show in addition to attending his vineyard in south Nashville.
