Amber Tamblyn on the set of "The Sisterhood of the Traveling Pants 2" August 1, 2007

Actress Amber Tamblyn was filming scenes today in the sweltering heat for her latest film, "The Sisterhood of the Traveling Pants" on St. Mark's Place and 1st Avenue in the East Village. She is a trooper. It was so hot and she was very nice, as was everyone on the set of this film (which also stars America Ferrara, and Alexis Bledel).
