Actress Leelee Sobieski is a mommy for the second time!

A rep for the "Here on Earth" star confirmed that she and her husband, Adam Kimmel, welcomed a bouncin' baby boy back in August. The pair, who are already parents to 4-year-old daughter Louisanna Ray, named their little one Martin.

The 31-year-old revealed she was pregnant with the couple's second child when she appeared at the Christian Dior Cruise 2015 fashion show in Brooklyn, N.Y., back in May. She never commented on her pregnancy, but the visible bump did all the talkin'. She also rocked a beaded bracelet that spelled out "Mommy."

Leelee, who lost her virginity to her fashion designer beau after they married in August 2010, revealed why she decided to start a family at age 26 that same year.

"We fell in love. I wish I had a girlfriend that had a baby. That would be so nice. I feel like I'm doing this thing that's really weird, but I look around me and realize that everyone has babies," she told New York magazine. "People in the middle of America have babies at my age."

Congratulations to the happy — and growing! — family!
