Sure, celebrities are flocking to Fashion Week in NYC to either check out the newest trends on the catwalk and/or to promote their own clothing lines, but there’s one other important reason for the stars to come out to NYC–the parties. Kate Bosworth looks pensive here, as if she’s trying to decide what she thinks of the new trends she’s spotted during the week’s events…or if she left her iron on at home. Wilmer Valderrama looks like he was skulking around, waiting for the next starlet to make her first bad decision. Ashlee Simpson and her mama can be seen taking in the fashion from their front row seats at a show, probably getting ready to get their party on after with Creepy Papa Joe lurking somewhere in the shadows.
