I don't think it is an act. Well, ripping her husband publicly is probably coldly calculated for PR gain. But I believe that is also some carefully guarded feelings being vented. There are other ways to kid around and poke fun at your spouse...but she gets mean, personal, and superior. That is not a happy woman. Even on the rare occasions the camera catches her smiling she still seems to convey that "I smell {excrement}" look. I'm not sure there is any one or any thing she is truly happy about.
