The mom-of-five, 42, captioned the photo above:

“We’ve had lots of questions about the cute kid popping up in our photos lately. We are excited to be in the process of adopting a new son! 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).

“He’s amazing, and we are 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.”

The new addition joins the couples’ five older children, Rebecca, 27, John Luke, 20, Sadie, 18, Will, 14, and Bella, 13.

Korie and her husband, 43, are no strangers to adoption — having adopted Will and Rebecca (who was an exchange student they consider family, though she was never legally adopted).

More than two years ago, Willie opened up to In Touch about his desires to adopt.

“I’ve done a lot of cool things in the past couple of years,” he said at the time. “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.”
