Isabella Rossellini never fails to impress me with her unique beauty. Yes, she lucked out genetically — having Ingrid Bergman as your mom can't hurt. But to me, the former Lancome model is really attractive because of her intelligence.
If I had to choose between being drop-dead gorgeous but not very bright, or being homely but brilliant, I'd choose the latter. Wit and charm are more valuable than good looks alone, and I'm not just saying that. (Think of the gorgeous guy at a party who winds up having the conversational skills of a banana slug. Compared to the less-handsome but funny and smart dudes, there's no contest.)
I know that you, dear reader, would never have to choose, as you are both smart and beautiful. But if you had to, which way would you go?
