Luke Bryan may have recently brought his "What Makes You Country Tour" to Hawaii for two shows in Honolulu, but it appears his trip wasn't purely for business. Luke's wife, Caroline, recently shared a picture of Luke joining his sons Bo and Tate and nephew Til for a shirtless round of golf at Maui's Makena Golf & Beach Club. In the picture, the boys can be seen smiling from ear to ear as they pose on the green with the Pacific Ocean in full view behind them.
