Well, wouldn't you know it, Sienna Miller really is one of the cool kids. This hipster icon has made it to the elite pages of the MisShapes website, where she was photographed partying it up behind the DJ booth at the popular New York nightclub.
Previous guests at MisShapes have included Madonna, Hilary Duff, and pretty much every hto rack band of the past couple years. You can see the rest of Sienna Miller's pictures from MisShapes after the jump, and don't forget to check out the whole gallery of cool people who were at the club on the same night as Sienna in the MisShapes gallery page.
