Welcoming a handful of fellow stars for an evening of cinema, Michelle Williams was front and center at the the Cinema Society & Piaget screening of "Blue Valentine" in New York City on Monday night (December 13).

Clad in a cute white frock, the lovely actress joined director Derek Cianfrance at the Tribeca Grand Hotel venue while chatting with guests including Alessandra Ambrosio, Olivia Palermo and Gabourey Sidibe.

With the film set for limited release in the States on December 31st, Michelle recently told press that she’s repressed any memories of filming racy sex scenes for “Blue Valentine,” because they were so explicit.

Miss Williams told, “I have purposefully forgotten it. My memory has been reduced to whatever is on screen, that’s all I can handle… I called my best friend, Busy [Philipps], one day after a long shoot and she said, ‘Maybe that is a sign that you shouldn’t go back to work.’”
