Congratulations are in order!

Former Joan of Arcadia star Amber Tamblyn, 33, and her Arrested Development alum husband David Cross, 52, have just welcomed their first child, a daughter named—well, we’ll get to that in a moment …

Tamblyn took to Instagram on Feb. 21 to break the news, posting a video of an adorable newborn foot along with the caption: “David and I are proud to announce the birth of our daughter, Dauphinoise Petunia Brittany Scheherazade Von Funkinstein Mustard Witch RBG Cross Tamblyn-Bey jr. #TheFutureIsFemale.”

Knowing Tamblyn and her comedian husband’s kooky sense of humor, we’re assuming this exhaustive name is a joke—but you never know … We do like the idea of naming a child after feminist heroes Beyoncé and Ruth Bader Ginsburg, not sure about the Mustard Witch part though.
