Luke Bryan's wife, Caroline "Lina" Bryan, is detailing what she considers to be a "normal" interaction in their family amid the holidays. "Nothing about my family is normal," Caroline, 45, wrote via Instagram on Saturday, December 27. "I was just taking a much wanted bath ... suddenly my mother in law and son just open the doors like it was Zero Dark Thirty ... sit down and just start having a casual conversation with me." She continued, "Oh ... and after that, I look outside and Luke is riding around on an excavator. Well, it is normal for us.
