Halloween is upon us, but for some celebrities, Halloween isn't just October 31 -- it's every day of the year. From the glamorous to the downright horrifying, these folks get dressed up in costume all the time. So on Halloween, instead of seeing them dressed up, we're taking a look at them without their masks.
Perhaps the most shocking is Marilyn Manson, the goth rocker known for wearing stark white makeup with dark lipstick and eyeliner, positively transforms when the cosmetics come off and his hair is more natural hue.
