Is it just me or does it seem that Kate in Jon and Kate plus 8 seem arrogant?

If you watched the show from the beginning it seems that Kate has really become arrogant while Jon has stayed the same. I like him. It seems that Kate has started to believe her fan mail, because she acts like a narcissistic celebrity. It seems the Roloff's in "Little People Big World" have stayed the same. Matt and Amy are so down to earth. I don't like to watch Kate anymore. What do you think?
