Yesterday, a bundled up Sandra Bullock arrived on the set of her new movie, Extremely Loud and Incredibly Close, looking chilly and bit a tuckered out. Perhaps the little man she is cradling in her arms might have something to do with her tired look. Did you keep her up the night before a shooting day, Louis? Didja? Didja? Regardless, Sandra is nothing if not professional, so upon arrival, she handed Louis over to his nanny and got straight to work on her scene. Eh, its all worth it, isn't it Sandy? To get to be able to do what you love to do and still have that adorable face to come home to everyday! Priceless! Check out more shots from Sandra's filming day yesterday below.
