Mine;
Jessica Alba
Rachel Stevens
Shakira
Roxanne Pallete
Pamela Anderson (and I don't give a **** what that says about me...)
I think people are missing the point of this thread tbh. I mean Julie Delpy's a lovely looking girl but if we're talking a one night no holds barred type of thing, surely there's 5 women with better claims than her?
