Katherine Heigl gym half shirt tights Beverly Hills

Who knew second-time-mom Katherine Heigl would wear a sports bra to the gym and show off her belly like that?!

Heigl recently brought home a new bundle of joy to add to the family, though no details have been released on the gender, age or nationality of the baby.

Katherine and hubby Josh Kelley adopted their daughter Naleigh, 3, in 2009, from South Korea.

The former Grey's Anatomy actress told Redbook in a 2010 interview: "My feeling about adoption is, Why not? There's nothing about it that makes it any less meaningful of a relationship in my mind ... My husband and I wanted to have a baby, and to us it didn't matter how it happened. Adoption has been a part of my life and a part of my family, so it was how I wanted to start. It felt natural and right to me."
