10. Kyle Richards

Show: The Real Housewives of Beverly Hills (2011)

We actually feel kind of sorry for Kyle Richards when we think about the circumstances of this fight, so there’s not much to applaud other than the fact that you have to admit she knows how to hit 'em where it hurts. While in a limo with her sister, Kim Richards, Kyle gets into a bit of a tiff with her and ends up exclaiming that Kim is an alcoholic, while Kim stares on like a lost puppy who's just been kicked or something. “You are an alcoholic! That’s right, I said it. Now everybody knows!" As a side note, apparently, Kyle’s fight may have done some good—Kim checked into a short stint at rehab not too long after this.
