Here here to AOG.
The most beautiful woman in the world is the woman (or man) who chooses to share their life with you, and will and and cry with you.
What this poll references is physical beauty, and that is but a small portion of what make someone really beautiful.
However (clambering off my high horse) I have to say that I've spent a few evenings in the company of Cheryl Cole (nee Tweedy), and latterly Fernandez-Versini, and hand on heart - she's shockingly beautiful in real life.
I mean...properly, properly beautiful.
She doesn't even appear to be the same species as the rest of us.
Other than than - Halle Berry five years ago had a serious claim on being the most beautiful woman in the world.
