The 23-year-old "19 Kids and Counting" star smiled from ear to ear while showcasing her bump at 38 weeks and 5 days, reported Us magazine.
"We are getting so close!!!" her family captioned the shot, while also asking fans to share their bump pics.
In another shot posted to their Facebook, the pregnant star smiles alongside Dillard, who holds a fishing pole.
Just last week the couple were feted with a baby shower at their local Olive Garden.
