Pharrell Williams has joined Rihanna's new TV show Styled to Rock.
The singer will star as a mentor on the fashion series when it makes its debut in the States on the Style Network later this year.
Rihanna is an executive producer on the show, which gives 12 up-and-coming designers the chance to create unique fashion pieces for a variety of celebrities.
The 10-episode series is based on the UK Sky Living original which saw Girls Aloud star Nicola Roberts, fashion designer Henry Holland and American celebrity stylist Lysa Cooper mentor the contestants.
Get Lucky star Williams has a number of fashion lines - including Billionaire Boys Club, Billionaire Girls Club, Bee Line and ICECREAM - and has also designed jewellery and accessories for luxury fashion house Louis Vuitton.
President of Style Media Salaam Coleman Smith said: "We are delighted to have Pharrell, who is a driving force in both the music industry and fashion world, serve as a mentor on Styled to Rock.
"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."
