Reba McEntire and Brooks & Dunn are breaking records in Las Vegas. They’ve added another series of shows at the Colosseum at Caesars Palace in 2017, making their residency the longest-running country music residency since the venue opened in 2003. The new dates begin in June and run through December. Tickets go on sale Friday. There are still five dates left this month for the 2016 run of the show, along with previously-announced dates in February and March of 2017.
