In honor of November being National Adoption Awareness Month, Thomas Rhett has opened up to E! News about the joys and challenges of adopting a child. "For me and Lauren, it was one of the most amazing but also challenging experiences of our lives, and it is something that totally changed our lives for forever. Willa Gray is literally the joy of my world. I cannot imagine living my life without Willa Gray today," Rhett says about adopting their first child from Africa in 2017. "It's one of those things that you should really think hard about, but also know that if you do it, you are giving somebody a chance at a life they may not have had otherwise." He also says adoption is "something we will more than likely do again. Lauren wants a million kids, so we need to get back on that train."
