Paris Fashion Week rolled into the weekend and continued to draw a star-studded crowd to the runways. Katy Perry showcased a handful of looks while Rihanna kept her all-black streak. The girls checked out Jean-Paul Gaultier on Saturday and Karl Lagerfeld earlier today although they split up for the Sunday shows. Mary-Kate Olsen and her boyfriend Nate went to the Giambattista Valli Pret a Porter runway this morning while Gwyneth Paltrow, who wore ankle length jeans, flew in from London to support her good friend Stella McCartney. The city is still full of celebrities flocking to check out the latest fashions although not all shows are getting great reviews.
