Pop Stars + Celebrities Covered in Blood [PHOTOS]

Blood and gore are not just the playing field of horror movies and metal bands. Plenty of celebs and pop stars get sanguine-soaked while performing, during photo shoots, on set and on magazine covers. Of course, it's all fake and for shock value.

In honor of the Halloween season, we've put together this slightly stomach-turning scrapbook of pop stars and celebs caked and clotted with the red stuff.

Remember, it's all fake. Or is it?

That's Kesha, gulping down plasma from a heart during 'Cannibal.'

Lady Gaga, or is that Lady Gore-ga? At the 2009 VMAs, she got her platelets on.

Look! It's Lady Gaga and her clotted cleavage in 2011.

Battered. Bruised. Bloodied. Biebs. In 2012.

Battered. Bruised. Bloodied. Timberlake. In 2002. Talk about a 'TKO.'

RPattz -- you know, Robert Pattinson or Edward Cullen -- not only sparkles. He also bleeds. He'll never be able to shed the vampire image.

Tina Fey was blood-spattered while filming an ep of '30 Rock.' Poor Liz Lemon.

Jennifer Love Hewitt looked believably bloodied.

Supermodel Heidi Klum showed off her circulatory system in costume.

The blonde and bloodied Bonnie McKee.

A blood facial for Kim Kardashian. Only in her world, kids. Only in her world.

Yes, that's a bloodied and beaten Matthew McConaughey.

Tom Felton, aka Draco Malfoy from 'Harry Potter,' got this way from filming. But dayum! He looked like he just wrapped a street brawl.

The 'True Blood' cast got literal on the cover of Rolling Stone.

Ryan Gosling's shirt was a little worse for wear, but thankfully his face was left untouched!

Cute Chloe Grace Moretz creeped us out as the blood-soaked, titular character in this poster for the remake of 'Carrie.'
