Fashion stars indeed!

Nicole Richie is set to offer her design expertise as a celebrity mentor on NBC's new reality competition series, Fashion Star, the network confirmed Thursday. The Winter Kate designer, 29, will join menswear designer John Varvatos and previously announced celebrity mentor Jessica Simpson on the series, which is hosted by Elle MacPherson.

"Jessica, Nicole, John and Elle make the most exciting team we have ever worked with on a reality television show and we are thrilled to feature such an extraordinary group of mentors and designers," Fashion Star's executive producer, Ben Silverman, tells Us Weekly in a statement.

Though she helms a fashion empire, mom of two Richie says her own personal style is much less thought out.

"I don't think it's as prepared as you'd think," she recently told U.K.'s In Style magazine. "I just grab whatever's around and put it on."

She says she's "pretty much a jeans and T-shirt type of girl and then I go from there."

Her style secret? "I collect a lot of vintage kimonos and vintage bed jackets," she says. "I'll throw those on, and a lot of the time it will appear that I'm wearing a completely different outfit, but I'm not."
