Pharrell Williams eBays his infamous Grammys fedora to raise funds for children's charity

The 40-year-old singer made quite the stir in the oversized Mountain Hat by British fashion designer Vivienne Westwood.
And now the infamous huge fedora that Pharrell Williams wore to the show is being auctioned off on eBay - with the proceeds benefiting his charity for at-risk youths.

The skyscraping park ranger-style headgear became a popular search on Google and even inspired its own Twitter account called Pharrell's Hat.

Pharrell put the big brown hat up for auction on Thursday with bidding scheduled to end on March 2 - and noted the winning bidder will receive a letter of authenticity.
The bidding opened at $200 and the high bid in just hours had reached $10,500.

'Hey @Arbys, you want my hat? Now’s your chance…,' Pharrell tweeted to his nearly three million followers on Twitter as he announced the auction.
The Get Lucky singer was referencing the American fast-food sandwich chain Arby's and its large red hat logo.

The outlandish hat was a major hit at the Grammys with stars such as Beyonce, Jay-Z, Ryan Seacrest and Ariana Grande posing for pictures with Pharrell wearing the lid.
