Jason Aldean's 18-month-old Memphis experienced an amazing life milestone this past weekend when he got to stay up past his bedtime to see his dad perform live for the very first time. "Usually he's in bed by the time we're playing our show, so he got to go to his first show tonight," Aldean told the crowd at Choctaw Casino's Grand Theater in Durant, Oklahoma, as he held his son. He then asked Memphis, "You havin' fun?" and waved his son's hand. When Memphis reacted with a scowl, Aldean again explained, "It's past his bedtime," before giving him a kiss on his cheek and returning him to his mom, Brittany Kerr, who was waiting on the sidelines.
