Rihanna's expert panel for the new season of her reality show Styled To Rock is getting a bit more expertise.

The singer and executive producer of the program hired producer Pharrell Williams and model Erin Wasson to be mentors to the shows competitors. Wasson is part of show as of Monday, while Williams joined last week.

The show is set to debut later this year on the Style Network. Comparable in format to Project Runway, it follows 12 up-and-coming designers as they create clothes, and style music stars and other celebrities. Like Rihanna, who recently debuted a collection for British chain River Island, the two new mentors also work on the design side of the fashion world in addition to their main claims to fame.

Williams has several clothing lines, including Billionaire Boys Club and Ice Cream. He has designed accessories for Louis Vuitton and collaborated with Moncler and the artist Takashi Murakami.

Wasson is a jewelry designer with her own line, Low Luv, and has worked with French brand Zadig & Voltaire for a collection based on rock star style.

"Pharrell's unique aesthetic and commitment to individuality combined with Rihanna's vision for this series will enable our aspiring designers to hone their craft and learn from the very people who set the trends," said Salaam Coleman Smith, president of Style Media.

Smith described Wasson as "a leading model and mainstay in the fashion industry. [Her] unapologetic approach to fashion and free-spirited style will give the 'Styled to Rock' designers invaluable insight."

"With Rihanna as executive producer and Pharrell and Erin as mentors," Smith continued, "our designers will gain incredible experience while also being challenged in new ways as they compete to earn the title of America's next trendsetting designer."

The first season of Styled To Rock appeared on British television channel Sky Living in 2012. The panel including street wear designer Henry Holland, former Girls Aloud singer Nicola Roberts, and celebrity stylist Lysa Cooper.
