A third sweetly wrote: "He's such a cute combo of you two!" while a fourth added: "Happy birthday Bo. Next year you get your license and give your parents a fright." Bo's birthdays come at a special time, as they've coincided over the last few years with his dad's appearances on American Idol.
Luke is a dad to five children – he shares sons Bo and Tatum "Tate" with wife Caroline, and adopted their nephew and two nieces, Til, Jordan and Kris, the children of Luke's late sister Kelly, who died in 2007, and her husband Ben "Lee" Cheshire, who passed away in 2017, caring for them in his Nashville home.
