Nicole Richie has already translated her trendsetter status into a full-fledged career as a designer, and now she's bringing her style expertise to TV. Nicole joins forces with fellow fashion success stories Jessica Simpson and John Varvatos to mentor up-and-coming designers on NBC's Fashion Star, which debuts this evening at 9.30 p.m ET on NBC. Nicole chatted with us recently to talk about the project. She explained what sets this series apart from some of the other fashion-focused reality competitions out there, shared her advice for young designers, and talked about what she wished she knew before starting her own lines.
