At the NYC screening for her film, The Private Lives of Pippa Lee, Blake Lively showed off some of that famous Gossip Girl cleavage in a low-cut, white blazer. While her boyfriend, Penn Badgley topped his suit with a gray beanie for warmth, Blake displayed her long, sexy legs in a pair of short black shorts.

The movie’s other star, Robin Wright Penn too displayed a dramatic new look with a new, dark hair color. After filing for divorce from her husband, Sean Penn, the actress has also tossed aside her blond do in favor of some darker locks. Robin also showed off a toned figure in a body-hugging midnight blue mini dress.

French actress Marion Cotillard also braved the cold weather in a sleeveless dress while Penelope Cruz let down her long hair and kept warm in a black suit and a pair of leather thigh-high boots.
