As fans of “Vanderpump Rules” saw on last week’s episode, Katie Maloney and Stassi Schroeder were confronted by former friend Kristen Doute. Don’t be shocked, this has been happening all season and to be honest, I don’t know who’s side I am on yet. Hell, fans aren’t even aware of what the real beef is between the former friends. However, we do know that it is serious enough that Kristen was not invited to Stassi’s engagement party for her upcoming wedding to Beau Clark. It is also unclear if she received a wedding invite.
