'Duck Dynasty': Willie Robertson's kids with Korie Robertson are loved equally

The stars of A&E reality show "Duck Dynasty," Willie Robertson and wife Korie Robertson, are proud parents to five kids they call their own, despite only three of the children being their biological offspring.

The couple runs a hunting supply business, Duck Commander, and raises their five children in Louisiana. 

Willie and Korie's adopted son, "Lil Will," has appeared in some episodes of the show. The couple, who have known each other since they were young children, are raising daughter Rebecca as a foster child, after having hosted her initially as an exchange student. Willie and Korie's biological children are John Luke, Sadie, and Bella.

In Korie's Twitter bio she calls herself the "proud wife" of Willie, and touches on their unique family situation: "Mom to four awesome kids plus a sweet exchange student who became ours. Love my big family. Thankful. God is good."

Willie's proud wife recently tweeted about the "Duck Dynasty" Christmas special, and posted a photo from "Christmas past," which shows all five kids together with their parents.
