Reese Witherspoon announced she was expecting her third child in March, but has stayed mum on her latest pregnancy - until this weekend.
The 36-year-old actress stepped out over the weekend, where she received the Gene Siskel Film Center's Renaissance Award in Chicago.
"Frankly I'm feeling very round tonight," she told reporters, according to People.
One reported suggested that Reese enjoy some of Chicago's renowned pizza while visiting.
"It's not easy," she explained. "I'm always feeling like I'd like to eat everything in sight!"
The actress is currently shooting "Devil's Knot" with Colin Firth in Atlanta, but after the film wraps she said she has more important things to focus on.
"It happens in Arkansas, and it's what I'd say is a very American story," she said of her latest project. "And, after I finish that, I'm going to take a little time off -- and go have a baby."
The newlywed actress is having her first child with husband Jim Toth. She shares custody of daughter Ava, 12, and son Deacon, 8, with ex-husband Ryan Phillippe.
