Pharrell Williams is auctioning off the headline-grabbing Vivienne Westwood buffalo hat that he wore to the recent Grammy awards. As soon as the singer stepped out on to the red carpet wearing the oversized, brown, brimmed headwear, his image pinged across the world and its own Twitter account was quickly created ( "chillin on @pharrell's head" don'tcha know).

Capitalising on his hat's seemingly instant iconic status, Pharrell has decided to raise some serious cash for charity by putting the ostentatious accessory on eBay. With 9 days and 7 hours left on the auction, bidding currently stands at $10,500 (£6,300) and the winning bidder will not only receive the hat and a certificate of authenticity but also that warm glow of charitability too.
