If you’re Lady Gaga, dressing up in costumes isn’t something reserved for October 31st, but for everyone else it means sexually explicit, innuendo rich, almost naked, sexed up renditions of the blue-collar workforce and the occasional “sexy” fairy tale character.

Celebrities take Halloween just as seriously (unless they’re Jessica Alba)… even Coco dressed up, and by dressing up I mean wearing more clothes than she usually does, which is no clothes at all.
