Missing Christian Siriano and his fierceness? Well, Project Runway's season 4 winner is dropping in on Bravo's Make Me A Supermodel Thursday (10 p.m. ET) to teach the final four contestants a thing or two about working the catwalk. The competition, hosted by Niki Taylor and Tyson Beckford (pictured towering over Christian), is winding down but the prize of $100,000 and a modeling contract with New York Model Management is still up for grabs. In addition to getting help from the Runway winner, the final four will also get inspiration when they get a surprise visit to from legendary supermodel Naomi Campbell. Now that's fierce.
