A source tells ET that Johnson, 39, took the photo, which was captioned “Jess-tation,” and that the star is eager to give birth following an, at times, grueling pregnancy.
“Jessica is definitely uncomfortable,” the source says. “This has been a tough pregnancy but she knows it will all be worth it when she’s holding that little baby. Her hospital bags are packed. Everyone is trying to be patient, but the family is so excited and counting the minutes until the baby is here.”
The couple is currently parents to daughter Maxwell, 6, and son Ace, 5.
