Kelsea Ballerini and Morgan Evans are coming up on three years of marriage. Kelsea says that they try to model their marriage after other successful couples like Thomas Rhett and his wife, Lauren. "You learn what's important. You learn how they do it. You learn how different couples manage it," she shares. "You find what works for you and then you respect each other for making it a priority. And with TR and Lauren, that is their priority no matter what. Them and their kids."
