The show itself is creepy enough - full of surprising plot twists, freaky monsters and eerie supernatural stuff. For example, season 2 takes place in an asylum run by nuns which is two of my different nightmares combined, yikes!!
Add to that a few of your favorite celebs in roles unlike anything you've ever seen them in before and American Horror Story will really freak you out. Seriously, watching Adam Levine get brutally murdered when you're used to seeing him sing happy love songs with Maroon 5...that'll really scare you. And he's not the only one...
Yep, that's Cam from Modern Family, but no, he's not the loud, bubbly half of your favorite TV couple. In fact, in the gif above, I'm pretty sure he's about to get shot in the head.
Okay so Stevie Nicks isn't as creepy as everyone else on this list because she just plays herself. But at the end of the episode she stars in, she somberly serenades everyone on the piano and it'll definitely give you chills.
He totally goes shirtless in American Horror Story, but it's nothing like his role in Magic Mike (unfortunately, amirite ladies?!) In fact, right after taking his shirt off, he gets viciously stabbed a bunch of times.
She brought all her Broadway drama to American Horror Story to play a creepily intense religious mother who unfortunately meets her fate by being forced to drink bleach. Not an ideal way to go.
Neil Patrick Harris
The only thing that Barney Stinson and NPH's character in American Horror Story have in common is that they both wear suits. He plays an insane magician whose "magic trick" goes awry when he actually saws a woman in half. Ouch.
She's starring in the upcoming season of American Horror Story, so we have yet to see what scary stuff she gets into. To me, she's the least surprising guest star choice, but maybe that's just because she already sort of creeps me out. Seriously, the Bad Romance video...gives me chills.
