The front row at last night's Marchesa show during NY Fashion Week was packed with stylish stars. Bar Refaeli, in a sexy black number and hot pink lips, sat next to Petra Nemcova while Mandy Moore posed for pictures with Emma Roberts. Kelly Osbourne made a solo entrance, Michelle Trachtenberg stood out in a dark blue dress, and Naomi Campbell mingled backstage with fellow models. Rachel Zoe brought husband Rodger Berman along for the fun after she presented her own collection earlier in the week. The designer had her son Skyler close by for the event and Rachel talked about how motherhood has mellowed her out and also shared her favorite pieces from the line. It's been an exciting week so far and there are plenty of NY Fashion Week celebrity pictures to see — check them out now!
