Okay, it''s not really the hat itself that bothers us here, it''s Ne-Yo''s sheer inability to wear it properly. While we can''''t work out whether he just needs to pull it down a bit or buy a smaller size, there''s definitely something not quite right here. Maybe give the hat a miss next time, Ne-Yo.
The hat was possibly the least crazy part of Nicki's outfit - not visible here, but she's wearing some kind of weird Barbie dress hybrid - but it's still pretty unfortunate. Bright pink and with some kind of Hello Kitty adornment, Minaj maybe just about manages to pull it off but without a doubt, anyone else would look ridiculous. Even more so, we mean.
Olly Murs was wearing this hat on Daybreak, and there's probably some context involved that we're not aware of. Either way, just look at it - Olly Murs wearing a pink cowboy hat. There's nothing more that really needs to be said.
Paloma Faith is an obvious one here; she's known for her crazy sartorial choices. Still, we did a double take when we came across this one. Did some kind of feathered bird die on her head? It certainly looks like it.
We've looked and looked at this one and it still doesn't make sense. Is that woolly monstrosity on Travie McCoy's head supposed to be a bumblebee? An animal? It's difficult to tell but either way, he shouldn't be wearing it. Take it off, McCoy!
Once again, Boy George was an obvious choice. This particular hat was worn to a film festival in Rome. Journalists from the show ''Le Iene'' did what, let''s face it, everyone would want to - they tried to knock Boy George''s hat off. After picking it up, however, Boy George slapped one of the reporters in the face. We wouldn''''t advise trying it yourself.
Jessie J is channelling her feline side with this furry nightmare. Perched on her head like it doesn't belong there, the shiny material and abundance of fur is something that makes it impossible to look away - and not in a good way. Better luck next time, Jessie.
Once again, it's not the hat, it's the way it's worn. Justin Bieber has pulled his beanie so far down over his eyes that he can't even see. Is that some kind of weird fashion statement that we're missing? Surely the 'Boyfriend' singer is going to have a few issues with that one.
Oh, Katy Perry. We're not even entirely sure that this is a hat - it looks like she just wrapped some material around her head and called it a day. While she's known for being quirky, surely there must be a limit - and if so, we think she's found it.
No, that's not a garden gnome, it's Chris Brown - and we'd look like that as well if we had to wear a hat like that. Surely all the singer needs is a fishing rod and stool to complete the look.
And finally, an honourable mention goes to Lady Gaga. While we could - and probably have - make a gallery dedicated entirely to her hats, this one has got to be the favourite. It does leave us with a lot of unanswered questions. How does she fit through doorways? Does she take it off in the car? And most important of all, who has to sit behind her in the cinema?
