It was definitely a working pregnancy for the star, who braved the hot summer temperatures in Georgia to film The Devil's Knot in July. Although Witherspoon was very visible around town, she spoke very little about the pregnancy.

"I'm feeling very round tonight," she said simply to the Chicago Sun Times on June 23. "After I finish [Devil's Knot], I'm going to take a little time off -- and go have a baby!" she added.
