It appears that Luke Bryan's trip Down Under on his "What Makes You Country Tour" will double as a family vacation. Luke recently posted a picture on Instagram of his family on the 17-hour flight to Australia, where Bryan is slated to play shows in Sydney, Melbourne and the CMC Rocks QLD festival. The picture shows Luke and his wife Caroline posing for a selfie with sons Bo and Tate, with Caroline writing, "Ready or not...here we come Australia! Tate just asked if we could play hide-and-go seek on the plane. I apologize...in advance...to everyone on this plane." It also appears that Luke's nieces, Kris and Jordan, and nephew, Til, are on the way to Australia, making the trip an even bigger family affair.
