Perhaps Francois welcomed his friend back with open arms because he understood what it meant to feel ostracized. In 1987, Francois was tasked with photographing then-billionaire Liliane Bettencourt, per The Guardian. She was the hair to the L’Oréal shampoo throne and immediately took a liking to the young artist despite their 25 year age difference. He was 40 to her 65.
She piled lavish gifts on him, things that most people can only dream of. There were Picasso paintings, life insurance funds, and of course cold hard cash. Twenty years later, Bettencourt's daughter began to suspect that this unlikely friendship was really a con perpetrated by Francois to sucker her mother out of cash and other valuable assets. She took legal action against him which led to a widely publicized trial.
Francois claimed Bettencourt was of "sound mind" when she bestowed upon him gifts worth €414m (over $500 million), including life insurance policies, paintings by Picasso, Matisse and Mondrian, manuscripts and cash." However, the court was made aware of the fact that Bettencourt was "suffering from increasing dementia and, by 2011, was unable to tell what year it was." Eventually Francois was found guilty in May 2015 and was sentenced to two and a half years in prison.
