"He's been with us since May, but we wanted some privacy and time for him and our family to bond before telling the world (It's a bit of an adjustment coming into this big, crazy family, ha)," Korie continued. "He's amazing, and we are all so thrilled to have another kid around the house. Couldn't keep the good news to ourselves any longer! We appreciate your prayers and support for our family!"

Korie and Willie are also parents to Rebecca, 27, John Luke, 20, Sadie, 18, and Willie Jr. and Bella, both 13. The couple adopted Willie Jr. when he was just a baby, and Rebecca, a former exchange student, became their foster child in 2004.

In 2013, Willie gushed over the adoption of Willie Jr.

“I’ve done a lot of cool things in the past couple of years. I’ve met presidents and been all over the world, but I still say the best decision we ever made and that had the biggest impact on our lives was the adoption of our son Will,” he told In Touch Weekly.
