With her growing belly on display, Mario Lopez and girlfriend Courtney Mazza attend the Chicago Healthy Living Challenge, held at the Navy Pier in Chicago on Saturday.
The television host and author, 36, and his lady love expect their first child this September.
“She looks beautiful pregnant and I just pamper her,” Lopez told PEOPLE recently.
“I’m constantly trying to feed her because I want to have a really healthy, chubby baby!”
