Is it a Harry Potter sorting hat? Is it a sack of potatoes? Is it stolen from Smokey The Bear? No, it's Pharrell Williams' attempt to upstage those Daft Punks at the Grammys. But it's not just the super producer who's had a bad hat day. Here's 11 absurdly terrible moments of head gear madness in popular culture.
Lady Gaga has never been a fan of dressing down, especially in the headwear department. Here she sports a hat made out of actual hair, which is as disgusting as it is innovative.
Lemmy's a bit sickly at the moment, the poor cherub, so we shan't mock him too much. We will however, suggest that it's a bit off to wear SS insignia on his hat, something which sparked a criminal investigation in Germany back in 2008.
Badly Drawn Boy spotted here in his natural habitat of a drafty attic, complete with knitted tramp's beanie hat, a prime example of early 2000s hobo chic. But minus the chic.
A gallery of the shittest hats in music wouldn't be complete without this guy, Jay Kay of Jamiroquai. Owner of the crappest headgear since King Harold took an arrow to the eye in 1066, Jay Kay and his hats - not to mention his music - gave us all something to laugh at in the 1990s.
Nicki Minaj rocked up to the 2012 Grammys with a fake pope on her arm and a red satin vagina around her head. The textbook definition of a strong look.
"A lime green wonky fedora with a diamante studded skull face? Sounds wonderful. It'll go a treat with my pink eyeshadow and a tribal symbol made out of eyeliner on the side of my face," is an actual thought Boy George had. Amazing.
What's worse than being kicked in a face by a horse? This hat, which is actually so repelled by Dappy that's its actually trying to make a break from the Celebrity Big Brother star's head. Godspeed, Dappy's horrible hat.
Proof positive that Rita Ora's a genius. I mean, how else do you describe someone who's cunningly combined a simple snapback with a Pierrot pom-pom? Oh sorry, did we say genius? We meant idiot.
Anti-fur campaigners look away now, for Rihanna has evidently skinned a rare breed of fuzzy bear and plonked its shaggy corpse across her head. More London Zoo than the Topshop accessories rail.
Madonna stole a white satin top hat from, we can only assume Gene Kelly or Fred Astaire, for her Sticky & Sweet Tour in 2008. Sadly, she did not then spend said tour performing show tunes from the 1930s.
Sure, Slash's trademark leather top hat looks good on Slash - mainly because it's probably holding his head together - but imagine it on anyone else. Chili Jesson or Alex Turner, say. Really makes you realise quite how gross it is.
