Pharrell Williams is set to launch a fashion range with Uniqlo.

The 'Happy' hitmaker has teamed up with the Japanese casual wear store to launch a new collection in association with his I Am Other creative collective.

The range will include men's and women's t-shirts and caps and goes on sale next month.

The 40-year-old music producer - who was nominated for an Oscar for his latest chart topping single - will also appear in the collection's television advert, with a track from his new album 'G I R L' providing the soundtrack.

The partnership will be a part of Uniqlo's UT t-shirt line, which is to receive a brand overhaul and be relaunched as The New Model T.

Pharrell's latest fashion project will be available in 14 different countries around the world, including the UK, from mid-April.

Uniqlo are currently said to be in talks to buy United States retailer J Crew in a deal which is estimated to be valued at $5 billion as founder Tadashi Yanai reportedly wants to turn his business into the world's largest clothing supplier.
