Ke$ha: No stranger to shocking people, Ke$ha's self-described 'garbage chic' style puts her at #20 on the list.
Justin Bieber: His fans, 'Beliebers', would be scary enough to get him on the list - seriously, they're like a cult - but there's just something else about him that gives us the creeps.
Nicki Minaj: Terrifying. Like a twisted, Halloween Barbie doll come to life, somewhere underneath the fake eyelashes and ridiculous hair is probably a normal looking person. Until we find that person, however, Nicki's staying at #18.
Boy George: The singer is nothing short of bizarre. It's not even the weird make-up or constant reliance on wearing hats, instead, he just looks sort of dead behind the eyes. Scary stuff.
Insane Clown Posse: Another one whose fans are almost as scary as they are, but ICP take the crown. They're dressed up as clowns... need we say more?
Tyler the Creator: Part of Odd Future, Tyler appears in the video for 'Yonkers' and appears to eat a live cockroach... and that's not to mention the part where he hangs himself with a noose.
Emilie Autumn: Known for her creepy doll-like make-up and weird gothic outfits, it's Halloween all year long for Emilie.
Skrillex: We're not sure if it's the greasy hair, awkward side parting or his past stint in emo band From First To Last, but Skrillex is enough to send shivers down our spine.
Taylor Momsen: At just 19, Taylor already has tons of eyeliner and the shortest skirts. Plus, she looks like she wouldn't hesitate to rip your throat out with her fingernails. Seriously.
Iggy Pop: Take a look at that leathery torso and tell us that's not scary. Point made.
Robert Smith: The Cure frontman looks almost exactly like a Halloween pumpkin - with maybe a little more hair and some hastily applied make-up.
Gene Simmons: The thing with Gene Simmons is, it's not the stage facepaint, the tongue or the costume (okay, it's a little bit to do with the tongue). The really scary thing is how he still seems to think that he's sexy. Ladies - BEWARE.
Lady Gaga: From meat dresses, to arriving to awards shows in an egg, to her costumes that always look like they wouldn't be out of place in the next Silent Hill movie, Gaga is terrifying.
Ozzy Osbourne: Okay, so maybe he's mellowed now that he's older, but seriously - the dude bit the head off a live bat. Apparently. Even if he didn't, he's the kind of guy that people wouldn't hesitate to believe it about, so that's good enough for us.
Alice Cooper: Give the man some respect for decade after decade of service to the dark side of music!
Grace Jones: The original scary lady. Creepy, intimidating and fierce, there's no doubt that we wouldn't want to run into her if we were alone in a dark alley. Or the middle of a flood-lit sports ground, for that matter.
Madonna: Seriously, Madonna is scary. The pointy bra, the insistence on flashing, and above all her sheer unpredictability get her to #4 on the list.
Slipknot: An obvious choice, but no less valid. Have you seen those masks?
Marilyn Manson: The man, the legend, Marilyn Manson. With his entire persona and image designed to scare - including taking his surname from the infamous Charles Manson - it's no surprise that he succeeds. But if Manson only places at No.2, who on earth is at the top of the list?
Chris Brown: Weird tattoos, criminal record and a very unapologetic attitude - not to mention the amount of fights he's got into. Chris Brown is the number one scariest celeb. Let's just hope we don't run into him this Halloween or ever.
