The Zero Dark Thirty actress posted a photo of herself from her younger years on Facebook yesterday.
In the adorable pic, Chastain wears oversized white sunglasses and over-the-top braided pigtails. Despite the silly hairdo, Chastain still has the same red hair and freckles we've come to know and love.
Chastain captioned the pic, "Ok everybody, here's a pic for you. I guess I've always been on the creative side. What a goofy kid, right?"
You say goofy, but we think the flashback snapshot is too cute for words, Jess!
