Without trying to quibble, i find a disconnect between Oden's title and the question he poses.
Intelligence is always a huge plus, but how we measure it or you express it can vary greatly. Personally, I like feistiness (or sauciness at elast) as well. But to me those don't really equate to beauty, unless you really mean inner beauty. Even then I know people who aren't necessarily of distinctly above average intelligence (beggin the question of how we measure that) who I find to have great inner beauty (.i.e, i find their character admirable.)
I don't know whether this takes us away from your intended subject, but I certainly don't find conventional beauty (again, measured ???) to correlate all that much with how interesting or sexy I find someone. As examples, I find Grace Kelly to be extraordinarily beautiful, but she isn't an object of erotic fantasy for me because I just don't find her persona appealing.

I'm just saying that the most beautiful people to me haven't been the best looking from conventional standards. They were, of course, absolutely gorgeous to me.
