Amber Tamblyn first delighted us with the joys of sisterhood more than 10 years ago in The Sisterhood of the Traveling Pants, and now she is branching out to motherhood. The 33-year-old actress is expecting her first child—a baby girl—with husband David Cross, she confirmed on Instagram.

“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,” she said in the post's caption (an excerpt from a personal essay she wrote). “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.”

The actress and her Arrested Development star hubby recently celebrated their fourth wedding anniversary with a hilarious post. “Happy 4th wedding anniversary to the most talented, wonderful, handsome, compassionate, inquisitive, kind, loving and understanding person I have ever known… Me. I love you, Me. And also David,” she joked.

We have a feeling that this compassionate star is going to make one heck of a mother. Congratulations to the happy couple!
