Katelyn Brown shared a heartfelt Father's Day tribute to her husband, Kane Brown, calling him the "best dad in the world." The post included photos and a video of the couple singing to their eldest daughter, Kingsley, via FaceTime. Kane has been open about his role as a girl dad and his desire to give his daughters the life he never had. He recently missed Kingsley's dance recital due to touring but Katelyn stayed back to be a "dance mom." The couple performs together on Brown's Drunk Or Dreaming Tour, which runs through September.
