During An Evening With Reese Witherspoon in Chicago on Saturday night, the 36-year-old actress admitted she was 'very excited' about the latest addition to her brood, and confessed she wanted to 'eat everything in sight!'
Despite her hard-to-miss bump, Reese had so far steadfastly refused to comment on her pregnancy, but joked that she was struggling not to scoff some of her favourite dishes whilst in Chicago - including deep pan pizza!
"It's not easy," she said. "I'm always feeling like I'd like to eat everything in sight!"
The star stayed mum however when journalists asked her about the baby's sex and if she had chosen any names.
Reese already has two children, Ava, 12, and Deacon, eight, from her marriage to Ryan Phillippe. This is her first baby with new husband, Jim Toth, whom she married in March, 2011.
Always a bit odd when stars say nothing about their pregnancy when they are quite so obviously expecting, isn't it!
