A huge congratulations is in order for Amber Tamblyn and her husband David Cross! They just welcomed their first child into the world.

The Sisterhood of the Traveling Pants star chatted with Glamour magazine back in October when she made the big reveal. She said, "I've been thinking about motherhood a lot lately. What it means to be one, what it means to have one, what it means to know one, what it means to make decisions as one and have conversations as one. Motherhood has been heavily on my mind because I am going to be a mother soon. I'm pregnant, with a daughter on the way."

Fans of Amber's went absolutely wild over the news. Now, she has finally announced the birth months later and we can hardly contain our excitement. She posted a video on Instagram 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."

Aww! While this video is seriously so freaking adorable, we have a feeling Amber is just trying to be funny in her caption. Of course, celebrities have been known to name their children some pretty unusual things, but this is REALLY out there. There haven't been reports just yet on what the actual name of her daughter is, but there's no doubt that it's anything but beautiful.

Ever since she announced her pregnancy, her Sisterhood of the Traveling Pants co-stars have been nothing but supportive. Blake Lively even posted a photo on social media rubbing Amber's belly! None of them have acknowledged the birth just yet on social media, but it's only a matter of time until the tributes start rolling in.

Amber and David have been married since 2012 and we're so excited to see how their family grows and develops with their baby girl now in the world.
