New York Fashion Week has sadly come to an end?but that's not without a big finish. Marc Jacobs, Calvin Klein and Ralph Lauren all put on amazing shows including an epic catwalk appearance from one of the world's greatest popstars. A new model (with a very familiar face) closed the Marc Jacobs show yesterday?you might know her as Lady Gaga. The popstar slayed the runway right behind, none other than, Kendall Jenner.
