Blake Lively Stuns in Never-Before-Seen Pregnancy Photo

Party of five! After announcing her pregnancy at husband Ryan Reynold’s Detective Pikachu film premiere in May, Blake Lively reportedly welcomed the couple’s third daughter earlier this summer.

And while the notoriously private couple has yet to share baby no.3’s name, Blake did take to Instagram to announce her partnership with Amazon Baby Registry to support the Child Rescue Coalition via a never-before-seen pregnancy photo.

Channeling her inner Serena Van Der Woodsen, the ultra-pregnant former Gossip Girl star dazzles in an embroidered black slip dress and oversized hoop earrings.

Lively, already mom to 4-year old James and 3-year-old Inez, took to Amazon to share her must-have baby registry items because, “my friends are popping out kids and I’m sick of having to type up a new ‘must-have’ list each time. I’m not THAT good of a friend.”

Lively’s registry includes products from pal Jessica Alba’s The Honest Company, Burt’s Bees baby line, and a host of diverse and feminist-friendly children’s books.

Congratulations to the growing family of five! We’re on the edge of our seats waiting for photos of their obviously genetically blessed baby.
