Michelle Williams in Erdem at Late Show Pictures

Michelle Williams posed for photographers before entering the Late Show With David Letterman studios in NYC last night. She was decked out in a floral dress from one of her go-to designers, Erdem. The interview Michelle taped will air on David Letterman's Friday episode. Michelle's home in NYC to spend time with her daughter, Matilda, and friends, but she clearly hasn't stopped making the rounds to chat up her movie My Week With Marilyn. Her role in the biopic earned an Oscar nomination in the category of best actress, and Michelle recently admitted to feeling surprised at the honor. Her name was the last of five to be called, and Michelle explained her reaction last week on the Today show. She's used to waiting for her name to be called, saying, "[It's] alphabetical. My whole life, I'm always the last to be called for any sports in school . . . . it's a "W" problem."
