In January, Livingston announced her pregnancy in an Instagram photo. “Round and round we go! I’m 15 weeks pregnant in this shot and I’m SO excited for our newest addition to the Goldblum family, arriving early April,” she captioned the photo.

Shortly after the birth, Livingston shared this adorable photo on Instagram, writing in the caption: “I can’t believe it’s been a week already! River Joe Goldblum was born 4/7/17 at 8:53am. Charlie Ocean is such a sweet and caring older brother. We couldn’t be happier!!! @jeffgoldblum is our rock and continues to be an exceptionally loving and passionate father! Love my boys!!!”
