JASON ALDEAN posted a great photo yesterday that was taken in Vegas over the weekend. He's at a crowded bar standing next to Luke Bryan, Russell Dickerson, and Thomas Rhett. They all look a little over-served.BRITTANY ALDEAN posted her own photo from what looks like the same bar in Vegas. She's hanging with Preston Brust's wife Kristen White, Russell Dickerson's wife, Kailey Dickerson . . . and Thomas Rhett's wife,Lauren Akins. Looks like a lot of the country stars roll together! Wonder what they were talking about??
