Just like King, Bilson had to tape a season of Hart of Dixie while pregnant. King added that she was on hand for Bilson on the set to make sure that the mom to be and the growing baby inside of Bilson's belly was taken care of.

"People forget that she's growning a human being inside. I had to get IV fluids because it was so hot when I was shooting in Burbank, but I never wanted that to happen to her. I was always super, super, super protective of her and her child."

The duo along with their Hart of Dixie cast recently wrapped filming for the highly anticipated fourth season. While rumors have circulated that it is the final season for the popular series, nothing has been confirmed yet. The season premiere is slated for early 2015.
