Reese Witherspoon talks baby no. 3, acting hiatus

Reese Witherspoon is gearing up for her third baby, which means she'll be taking a break from moviemaking.

The Gene Siskel Film Center honored the actress with their Renaissance Award at an event at the Ritz-Carlton in Chicago on Saturday. Witherspoon, 36, spoke about her pregnancy for the first time, telling reporters who remarked that she was a glowing mom-to-be, "Thanks, but frankly I'm feeling very round tonight."

She also said that being in the Windy City, known for its pizza, was stirring up some pregnancy cravings. "It's not easy," she said. "I'm always feeling like I'd like to eat everything in sight!"

Witherspoon, who is married to talent agent Jim Toth and has two children from her previous marriage to Ryan Phillippe, has been finishing up production on her latest movie, "Devil's Knot." The film, which is shooting in Atlanta and co-stars Colin Firth, is about the 1993 murder of three young boys in West Memphis, Arkansas. Three teenagers -- later dubbed the West Memphis Three -- were accused of killing the children as a part of a satanic ritual, despite a lack of physical evidence. The trio were released last year.

Talking about the film, Witherspoon told reporters, "It happens in Arkansas, and it's what I'd say is a very American story." Adding: "And, after I finish that, I'm going to take a little time off — and go have a baby."
