How do celebrity crushes relate to real life?

This girl almost literally drools when she sees a picture of Will Smith. There are a million guys who like her, and she could get any guy she wanted. But the only guy she seems to have feelings for is me. I'm the least like Will Smith of anyone you could imagine, I mean none of her friends are like him either, but I'm (relatively) short, kind of buff but I have a build like a fat biker, I'm white, and it goes on. So why me?? I would just enjoy it and not care, but I'm scared that she'll find a guy who really IS like Will Smith and not like me anymore!
