Katherine Heigl already has two daughters. But her son on the way is the first biological child for the actress — and with being new to pregnancy comes being new to incorporating a growing baby belly into her work.
“Now I feel like [viewers are] only going to be watching that, and [they’re] just going to be like, ‘Oh, she’s hiding her baby bump in this scene,’ ” the star of the upcoming CBS legal drama Doubt tells PEOPLE.
“But yeah, I am,” Heigl, 37, admits. “That’s what I’m pretty much doing … in every scene.”
