They were lovers a long time ago. He's got a big heart this guy flaunting her like that in front of his children and his wife.
and welcome. Hmmmmmmmmm.
I do hate sounding like an old pearl-clutcher (even though I am one), but if Albert has Caroline to be there by his side, then an ex-lover now "friend" such as Sharon Stone would seem to be, as they say, "surplus to requirements."
However, Sharon does provide a Hollywood celeb/glamour element, which I guess is important at these charity do's. People aren't going to pay $$$$ per plate just to meet or be seated with Average Joe.
