The upcoming NBC show will feature 14 designers hoping to win a multi-million prize which will allow them to launch their designs in one of America's biggest retailers.
Nicole Richie, Jessica Simpson and John Varvatos serve as the mentors who will help advise and guide the designers through the process.
Macpherson said: "[The show] has everything. Stories that are heart-rending and motivating. Wonderful feedback from people who really know what they are talking about, whether it's the buyers or the mentors. Glamour, fashion shows, the musical acts that there are. It's just a cool show."
The supermodel added: "In life it takes more than passion and opportunity to realise a dream. It takes commitment, dedication, humility, concentration, persistence, and courage, and these are some of the things we see in the designers."
Watch Elle Macpherson talking about Fashion Star below:
Each episode of Fashion Star will begin with a fashion show based around a weekly challenge, where the retailers will be able to bid on designs that they want to buy and exclusively carry in their stores.
Designers who do not sell any designs that week could face elimination, although the celebrity mentors will have the chance to save one designer.
Viewers will be able to buy the winning designs as soon as each episode ends.
Fashion Star premieres Tuesday, February 13 at 9.30/8.30c on NBC
