Michelle-Marie Heinemann and Jon Heinemann are suing their children's private school for nearly half a million ($415,000 to be exact) after allegedly getting tricked into buying a $50,000 finger-painting designed by a class of kindergartners. The Heinemanns, who are regulars in the NYC social circuit, pulled children Hudson and Hyacinth out of the school and suing for damages-- "including $20,000 tuition to a new school, forfeited class fees for his little sister Hyacinth Cornelia and Hudson’s $60,000-a-year chauffeur." We took a look at their party history to find out just how much the family dominates the NY social scene.
