Jennifer Hudson joined Project Runway host Heidi Klum and judge Nina Garcia at today's season finale presentation in NYC. Jennifer is the latest star to make a cameo following in the footsteps of last year's guest host, Jessica Simpson. It's been a busy kickoff to Fashion Week for Heidi, Nina, Jennifer, and fellow judge Michael Kors. Last night, Michael hosted celebrities like Nikki Reed, Kate Upton, and Debra Messing at his Manhattan boutique as part of Fashion's Night Out festivities. Jennifer partied with Nicole Richie at a QVC bash. Heidi, meanwhile, stopped by former Project Runway winner Christian Siriano's new boutique to do some shopping and wish him well.
