>> While Chanel Iman is firing off voice-over dispatches from Fashion Week, Coco Rocha has been busy taping her new video series, "Insider's Guide to Backstage," in between catwalks.  There are six episodes total, and the first has just premiered, following Coco backstage at Matthew Williamson, where she enlightens us on such model wisdom as how to get away with stealing runway shoes you're not supposed to and how to hide from cameras you don't want to talk to.
