Joshua Jr. joins older sisters Naleigh, 8, and Adalaide, 4, in the family of five. Heigl revealed how she shared the news that she was pregnant with Naleigh and Adalaide -- whom she adopted in 2009 and 2012, respectively -- in a new interview with People.
"[The news] was a little confusing for the girls because they'd be like, 'I grew in your tummy?' And I had to explain, 'Well, you didn't actually grow in my tummy, but your dad and I are your parents,'" she shares.
The Heigl family is no stranger to adoption. Heigl's older sister, Meg, was adopted from Korea.
"My mother used to say this too: 'It doesn't matter how they come into your life,'" the former Grey's Anatomy star tells the magazine. "'The moment they put that child into your arms -- whether you just [gave birth] or whether they just arrived from Korea -- they're yours.'"
ET talked to the Doubt star in September, when she adorably talked about struggling with "pregnancy brain."
"Usually I'm pretty good at memorizing," she explained. "I can do that pretty quickly. It's like the only thing I've got. So, it's really been eye-opening to me to struggle with that."
