Yes. On Larry King they behaved as if they had just begun dating and really didn't know each other.
They probably don't know each other at all. How much time do you think they actually spend together?
Given that he married her for her money, she surely couldn't have married him for his looks. I'm still trying to figure that one out. He got money but what exactly is she getting out of this deal - proximity to power (or some facsimile thereof)?
