Expecting her first child later this year, Leelee Sobieski has a theory when it comes to her pregnancy cravings.
“I think I like eating what little kids eat,” Sobieski told PEOPLE at the season opening of the Metropolitan Opera on Monday in New York City.
Chowing down frequently on macaroni and cheese, Sobieski, 27, says that she is preparing for the baby by doing two things: relaxing and eating lots of ice cream. However the Joan of Arc actress is unable to eat as much of the frosty treat as she used to.
