Huff posted a similar photo, captioning his smiling pic, "mom & dad."

Sadie's mom, Kori Robertson, also celebrated the big news with a loving tribute to her daughter and son-in-law.

"Big, crazy, awesome news!! My baby is having a baby. @legitsadierob and @christian_huff y'all are going to be the most amazing, fun, joyful parents," wrote Korie.
