Who is your "forbidden lust"?

No, I don't mean your damn cousin or sister. Here's the rules:

1. It has to be someone well known. A celebrity or what have you.
2. It has to be someone you're not supposed to think is hot, or someone other people would not normally think is hot.

Mine is definitely Hillary Swank. In Boys Don't Cry. Another good example is a young guy I work with, maybe 18, who thinks Barbara Streisand is really hot.
