There’s something going around and it isn’t the flu. A zombie pathogen, perhaps? AMC's "The Walking Dead" returns on Feb. 10 and to celebrate, our friends at Snakkle.com take a look back at famous celebrities who bit off, well, enough for them to chew… and craved flesh at some point in their careers. Guess who’s who and find out how they caught the flesh-eating bug!

Whitney Port
“The Hills” star Whitney Port took her long legs and stylist’s eye to NYC, starring in “The City” after the success of “The Hills.” While we can’t imagine the golden-tressed Port in anything other than perfectly applied lipstick and blush, here she is in 2012 in a monstrous makeover for an American Red Cross Zombie Blood Drive campaign.

Madison Lintz
Little Madison Lintz has come a long way since her guest spot as Natalie in the TV series “It’s Supernatural”, but she hasn’t strayed too far from the “supernatural” part. She makes cute look scary as Sophie in AMC’s hit show “Walking Dead.” Such a bummer her character went zombie and wanted to eat everyone’s brains.

Peter Jackson
“Lord of the Rings” director, Peter Jackson stayed true to his sci-fi roots when he participated in the American Red Cross Zombie Blood Drive campaign. Hollywood costume makeup meets the undead? Count him in.

Bill Murray
Talented comedian and actor, Bill Murray is famous for being a recluse. But the star made a brief 2009 cameo in the movie “Zombieland,” playing himself…as a zombie. Murray proves that a human-playing-a-zombie isn’t the best practical joke to play on someone in this dead funny film.
