America Ferrera and Amber Tamblyn may not be sisters by blood, but they certainly share a special bond. The Sisterhood of the Traveling Pants costars recently reunited to have a play date with Amber's daughter, Marlow, and it's too cute for words. Not only did the Superstore actress capture the moment by sweetly kissing the 6-month-old on the head, but we can't get enough of her caption, "#thefutureisSisterhood." This also isn't the first time the actresses have reunited. In May, Blake Lively and Alexis Bledel stepped out to support Amber's directorial debut at the NYC premiere of Paint It Black. And with a third Sisterhood movie becoming more and more likely, their friendship will only continue to blossom.
