You know, if my girlfriend slept with a famous man i'd be severely egged off, and i'd kick her whore arse to the curb. I wouldn't sleep with a famous woman either whilst i'm in a relationship (yes, i mean it. Even if she was naked and begging me to get into the bed. And yes, i am strong enough. Just trying to counter the obvious replies.)
But since i'm in the thread i may aswell make a list of people i'd like to beg me into bed, so that i could turn them down:
Scarlett Johansson
Jennifer Anniston
Jessica Alba
Ellen Page
Eliza Dushku
