Who's the Most Famous Natural Redhead Woman in Hollywood?

I thought this was an easy question and assumed it would be Emma Stone or Christina Hendricks aka Joan from "Mad Men."

Then I found out that surprisingly they're both not natural redheads. Apparently Stone is a blonde which just seems weird since she's so synonymous with having red hair.

This is like finding out Don Draper lost his mojo all over again.

What's next?  An HBO show not randomly featuring nudity just because it can.

Naturally red headed women must feel like the Na'vi because some outsiders just adapted their look and seemingly became the best representation of it.

But seriously, I don't know the answer to this question.  Lindsay Lohan doesn't really count because she's just famous for failing at life.

Does anybody know the answer?
