Is she a crack head Duh! Of course she is! Do I still want to see here naked? Duh! Of course I do. The knowledge that she does hardcore drugs does not in any way change the fact that she is a somewhat attractive chick not wearing clothing.
I do disagree with the choice of theme though. Doing a chick up like Marilyn has been done to death. Plus I prefer red heads. I would rather see her with red hair and no make-up with a needle sticking out of her arm than airbrushed to look like an old school pin-up girl. But thats just me I guess.
