Kate Moss checked out the Saint Laurent show last night at Paris Fashion Week with her husband, Jamie Hince. Salma Hayek was also in the front row with her spouse, Francois-Henri Pinault. Jessica Chastain, the face of YSL's Manifesto perfume, stepped out as well for the Spring 2013 event. Kate wrapped up a busy day that also included watching the Spring 2013 Stella McCartney show with other stars like Salma and Jerry Seinfeld, and later celebrating with Stella with a shopping excursion to Colette. Kate and Salma are among the many celebrities at Paris Fashion Week, and we'll see more before the stylish fun wraps up tomorrow.
