Celebrity fashion-lovers flocked to Paris for this week's haute couture fashion week. Kicking things off in style was Versace's runway presentation, drawing Gleeks Lea Michele and Matthew Morrison as well as Jessica Alba and Mad Men's resident siren Christina Hendricks to sit front row, while Christian Dior, Armani Privé and Chanel attracted royalty of the real (Princesses Charlene and Tatiana), and Hollywood (Sophia Loren), variety. From day four, Valentino brought the heavy-hitters with Olivia Palermo, Clémence Poésy and stylish duo Kim Kardashian and Kanye West in attendance. Louis Vuitton didn't put on a show, but the celeb-filled store opening brought the level of style we've come to expect from a week at Paris couture fashion week.
