Wissam Al Mana, is "what's his name's" name. A Google search yields information about him. But I know that's not what was really implied. No, this isn't a man vs. woman thing. Rather, it is a simple observation as to how Janet is being scrutinized in this, as if she was a lone party in her marriage. I'd ask the same question if an incident involved all men or all women who were involved in an action, not just the one that was "known."
None of "knows" any of these famous/wealthy people. I suppose for some, though, it is a great source of amusement to speculate on the negative aspect of their lives. Gives them a break from complaining about QVC hosts and vendors.
