The 38-year-old actress bragged to ET's Nischelle Turner at the Unforgettable junket about her and husband Josh Kelly's three children, and revealed why she decided to adopt daughters Naleigh and Adalaide. "When you're a kid and growing up and you're like, 'I'm going to get married someday and have a family,' I knew for certain that I wanted to adopt from Korea," Heigl said of adopting her oldest child, Naleigh. "My sister's Korean and she's my big sister and hugely important to me and my best friend. I just knew I wanted my family to sort of look like the one I came from. So I always knew I was going to do that."
As for Adalaide
, the former Grey's Anatomy
star added, "I never thought I would adopt domestically, but that just sort of gracefully happened and it did feel like grace." Heigl quipped that Adalaide is a "spit fire."
"She's going to be seriously running the world one day. She's terrifying," she noted. "Fierce little girl."
Needless to say, Heigl -- who just gave birth to son Joshua in December -- loves being a mom. "It's so much better than I could have ever imagined, my life and family," she gushed. "It's just trying to remember that and be grateful and try and hold onto it 'cause you do get caught up in the minutiae."
In February, Heigl also dished to ET about her approach to losing the baby weight
. The actress credited not “not beating" herself up, for her amazing post-pregnancy figure. Check out the interview:
