Dumb blonde?

I had a thought the other day, and I want to share it - don't laugh until you've heard my explanation, m'kay?

Jessica Simpson is the smartest woman in showbusiness right now.

No, seriously, think about it!  Here is a woman who has made her entire movie career off of her boobs and butt.  And yet she's never once shown either of them in their full, bare, beautiful entirety.

That takes brains.  Prove me wrong.
