This woman is the most ridiculous character of all the characters on the "Reality" show series Real Housewives of New York/New Jersey/Orange County/Beverly Hills/Atlanta and the like.
First of all, she is not royalty. Royalty is born royalty. They are born into a family which teaches them values, manners and gives them a good upbringing. She was born a nobody and happened to marry a Count. He has since left her, but she continues her 'holier than thou' attitude.
This is not her worst trait however. It is one thing to want to cling to status and symbol. Everyone has this urge deep inside them. It is not even the fact that she makes taxi drivers call her "Countess" rather than merely "Ms." or "Luanne". This is just the typical bullshit that comes from people not born into money or aristocracy, who would do anything to hold onto it.
It is the fact that she throws the word "class" around with such ridiculousness. When she gossips like a high school girl, when she causes a scene in front of people's children, when she meddles in other people's lives to create drama, when she talks badly about other people... that isn't bad class or bad taste.
It appears that it is only those who dare to call her on this behavior, those who dislike her or say something negative against her which lack "class".
This is hypocrisy at it's finest.
