Luke Bryan recognizes that there are a lot of good things about being a father, and those seem to increase the older his kids get. In fact, the superstar admits this time, right now, may be the best it has been since he became a dad more than a decade ago. "As they grow older it gets easier to let them tag along," the Georgia native, who is raising sons Thomas "Bo" Boyer, 13, and Tatum "Tate" Christopher, 10, tells "They become little men and they become functional little microcosms of me. Their personalities are really different," the singer continues. Bryan and wife Caroline also legally adopted their nephew, Tilden, and took nieces Jordan and Kris into their care after the death of their father, Ben Lee Cheshire, in 2014. (Bryan's sister, Kelly — their mother — died in 2007.)
