We've spotted carbs and dairy products backstage, but the definitive sign that times have changed would have to be the Billy's Bakery red-velvet cupcakes being handed out at the W Lounge backstage. The decadent treats come in individual cardboard boxes with circular wire handles so you can clip the box to your bag, presumably for easy accessibility. (They've certainly come in handy for us while starving at a number of shows.) And we spotted Kimora Lee Simmons and Djimon Hounsou walking into the Barbie show with four of the edible accessories. Two were for her daughters and two were for her assistant, she claimed, somewhat unconvincingly.
