2011 New York Spring Fashion Week Celebrity Pictures

Fashion Week kicked off with a bang on Fashion's Night Out and since then NYC has been a frenzy of presentations, celebrities, parties, and designers. Some of our favorite stars, like Dakota Fanning, Beyoncé Knowles, Alexander Skarsgard, and Mandy Moore were in the front row checking out the Spring collections from talented designers like Calvin Klein, Jason Wu, and Michael Kors. The fun came to an official close last night with Marc Jacobs' runway show, and now things have started up across the pond in London.
