We’re all about the celeb mamas right now, with John Legend’s Mother’s Day tribute to Chrissy Teigen being one of the sweetest things ever and Eva Mendes shocking us with the news that she had her second baby with Ryan Gosling two whole weeks ago. It turns out there was another little one who made an appearance in time to celebrate Mother’s Day, as Jessica Capshaw has just announced the arrival of a new baby girl into the world, and the pic will make you squee with delight.

The 39-year-old actress, who you’ll recognize as Dr. Arizona Robbins from Grey’s Anatomy, posted the pic to her Instagram account showing off her newborn daughter, saying, “Josephine Kate Gavigan May 2, 2016,” adding, “I am endlessly grateful for her safe arrival and my heart is so full of love that it threatens to burst.”

Josephine is the fourth child for Spielberg-relation Capshaw (yes, Steven Spielberg is her stepdad) and her husband Christopher Gavigan, who she married back in 2004 — the pair are already loving parents to nine-year-old Luke, six-year-old Eve and four-year-old Poppy.

Congratulations to the ever-growing family!
