Michelle Williams joined a friend for a casual stroll through Brooklyn yesterday. The latest piece in her seemingly endless collection of girly floral dresses remained partially concealed under her black coat while her very platinum locks blew freely in the wind. Over the weekend, she welcomed her Blue Valentine costar Ryan Gosling to the Big Apple, where the pair met up for a special screening of their film hosted by Robert De Niro. Michelle recently gushed about Ryan's wild energy and generous spirit, though our dream couple are just friends in real life. Their intense onscreen chemistry earned an NC-17; however, The Weinstein Company is currently collecting signatures from supporters to have the rating appealed.
