Amber Tamblyn has welcomed her first child!

Congrats are in order for Amber Tamblyn and her husband, David Cross!

The couple has welcomed a baby girl - both Amber and David's first child.

The Sisterhood of the Traveling Pants star took to Instagram to announce the exciting news.

While celebrity baby announcements aren't usually humorous, Amber obviously had a few laughs with hers.

"David and I are proud to announce the birth of our daughter," she wrote in the Instagram caption. "Dauphinoise Petunia Brittany Scheherazade Von Funkinstein Mustard Witch RBG Cross Tamblyn-Bey jr. #TheFutureIsFemale".

The couple have yet to confirm what their daughter's actual name is.

Amber announced her pregnancy with an essay for Glamour magazine, in which she touched upon her passion for women's rights. "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," she wrote. 

She continued, "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. I think constantly about the world I am bringing her into."

Amber tied the knot with her comedian beau, 52, in 2012.
