Pharrell Williams has signed a deal with Adidas.

The 'Happy' hitmaker - who is currently working on a collection for high street brand Uniqlo - is thrilled to have the opportunity to design a collection using eco-friendly Bionic Yarn for the sportswear giant, which will debut this summer.

The 40-year-old musician said: ''Working with an iconic brand like Adidas is such an incredible opportunity. From the classic tracksuit, to growing up in Virginia wearing Stan Smiths, Adidas has been a staple in my life. Their pieces are timeless. This is an exciting partnership for both me and for Bionic Yarn.''

Adidas are equally delighted to collaborate with Pharrell - who is married to Helen Lasichanh - and thinks he's ''perfect'' for the brand.

Dirk Schoenberger, Adidas' sport style division global creative director, added: ''I am truly thrilled to work with Pharrell.

''He is a pop-culture icon who never fails to inspire, not just through his musical talent and craft, but through his many other interests. He is the perfect fit for the multi-faceted company that is Adidas.''
