Is that Kate of the TV show 'Jon & Kate Plus Eight' always mad about something?

Every time that I see her one of those TV tabloid shows, she always is. Now I don't know if it's true or not about her husband's cheating allegations, but if he did cheat, I can imagine that would be one reason that's she's angry. He claims that he hasn't cheated. Now on the other hand, I can see why he might want to fly the coop too. She stays riding that man. It's like he's 5 years old and one of the kids. Tonight they were saying on one of those shows, that they both are doing this act for ratings. I don't watch the show, do you think that's it? I think they said the show had over 9 million viewers last week.
