*Apparently, only Pharrell can prevent forest fires.

Twitter lit up as soon as Pharrell Williams hit the Grammy red carpet Sunday night with his brown Smokey the Bear chapeau.

The 40-year-old “Happy” singer earned seven nominations in five different categories — but the Internet was more interested in discussing the contraption on his head, which folks referred to as the Arby’s restaurant logo, Woody’s hat from “Toy Story” and even the Sorting Hat from “Harry Potter.”

And by Monday morning, the hat had it’s own Twitter account – with more than 15,000 followers.

Designer Vivienne Westwood is to blame for this.

“It’s a Vivienne Westwood Buffalo hat from when she was with Malcolm McLaren,”  the Producer of the Year winner told The Hollywood Reporter Sunday night. “It’s not vintage — I would’ve been really stylin’ if I had once from the ’80s.”
