Paris Fashion Week had another big evening with the Yves Saint Laurent show and the launch party for Mario Testino's new book MaRIO de Janeiro Testino last night. Lindsay Lohan smiled big and posed with the famous photographer, so it looks like any negative reviews of her Ungaro show aren't getting under her skin. Kate Moss and Jamie Hince attended both the fashionable events with a quick costume change in between. Kate admitted that Fashion Week can be exhausting saying, "You have to be so young to do this. I don’t know how editors survive." Katy Perry also pulled double event duty without her FW partner in crime Rihanna or her new boy that most of you think is the perfect fit, Russell Brand.
