Not only is she a pretty darn good actress, she's drop dead gorgeous (and most importantly) curvaceous.
Seriously. It's like what the wise prophet Sir-Mix-A-Lot said: "my annaconda don't want none unless you got buns, hun."
Truer words have never been spoken.
Most actresses go out of their way to be skinny and skanky. Scarlett, well, she's busty. And I like that.
