Pharrell Williams' hat is the fashion star of the night at the Grammy Awards - on Twitter.
The puffy brown Canadian Mountie-style fedora -- or should that be phedora? -- with a big brim was one of the night's boldest fashion statements.
Williams' choice of a tight red track jacket only added to the unconventional look amid tuxedos and evening gowns worn by other attendees. Like Prince's cane, Pharrell's hat had its own Twitter handle within minutes of Williams' first appearance on the broadcast, and companies like Gain and Arby's were trying to horn in on the attention.
Williams won producer of the year Sunday, his fourth Grammy.
