2014: Pharrell Williams' busy year

Here's a look at some of the fun things he got up to during 2014.

"This Is Not A Toy" Williams kicked off the year with his first curated museum exhibition "This Is Not a Toy" at Toronto's Design Exchange (DX) Museum in February. The show explored the conceptual toy as a fine art and design object through a vibrant mixture of music, video, vinyl, art and sculpture.

Uniqlo In March the star was signed up as ‘collaborator and spokesperson' for Uniqlo's UT t-shirt line, with his creative collective 'i am OTHER' hitting stores later in the spring.

Inspiration In April, Williams wrote a "social book" called "Inspiration" which was published online with its words erased for fans to guess. What a tease.

"G.I.R.L." The lover of both museums and women was back to exhibition curating with the launch of "G.I.R.L.", a feminist show at Paris's Perrotin Gallery.

'That' hat The hat that sparked a social media sensation when worn by Williams to the Grammy Awards subsequently went on display at the Newseum, Washington DC. Designed by Vivienne Westwood, the "Buffalo Hat" proved to be such a talking point that the singer later sold it on eBay, where it was bought up by fast food chain Arby's for $44,100, with proceeds going to charity.

Adidas Global sportswear brand Adidas Originals snapped up Williams for a limited-edition collaboration unveiled this September with new product packages revealed each month throughout October, November and December.

Ladurée The star turned his hand to pastry creation this fall, concocting two macaron flavors for luxury French sweet house Ladurée. The limited-edition cola and peanut butter-flavored treats went on sale in Paris exclusively at concept store Colette, which also declared October 13-18 "Pharrell Week".
