The actress opened up to ET last fall about blaming her forthcoming baby boy for her pregnancy cravings for sweets, saying, "It's lovely actually because I feel absolutely no responsibility for my behavior at all. It's great."

"If I'm not on set, I don't think about them that much. And I don't eat them because they're not around," Heigl explained on the set of her new legal drama, Doubt, back in September. "But on set, crafty always has a plethora of donuts in really pretty pink boxes and I can't stop thinking about them."
