Washington museum to display Pharrell's hat

Pharrell Williams' Grammy Awards hat will be displayed in a museum.

The infamous headwear - a bold Vivienne Westwood Buffalo hat - sported by the 'Happy' hitmaker at this year's ceremony was later sold to fast food restaurant chain Arby's at a charity auction for over $40,000 and will now go on loan to Washington DC's Newseum on August 22.
