Season 4 Winner: Christian Siriano

Impossibly "fierce" Season 4 champion Christian Siriano has been keeping busy since taking the crown. One of the boldest personalities ever on the show, Siriano has even been spoofed on " Saturday Night Live." The larger-than-life designer also appeared on " Ugly Betty" and "The Oprah Winfrey Show." His celebrity clients include Rihanna, Lady Gaga, Victoria Beckham and of course Heidi Klum. In addition to showing at New York Fashion Week, he designed a line of shoes and bags for Payless as well as a limited-edition makeup collection for Victoria Secret. Siriano released his style guide, "Fierce Style: How to Be Your Most Fabulous Self" in 2009.Reed Saxon / Associated Press
