Funny you should mention mannerisms. I too read mannerisms of certain white female celebrities that you can tell by her actions, demeaner, haircut, etc., just know how to take black pipe and those who can't. Julie gives of vibes that she can handle herself in the bedroom and give it back to a brother as well.
Side Note: I've built this "list" in my head of the white women in the mainstream media who I think can throw down in the bedroom and secretly have a thing for black men. Anyone else think this way...
