This might save you the time of googling -
A playboy model who was supposed to look like Marilyn Monroe. Married billionaire J Howard Marshall who was 60 odd years her senior. From googling, she was 26 and he was 89. It was claimed (presumably by the media) that she married him for his money. He died a year later and it turned out he had changed his will and left her name out of it. She started court proceedings stating that he had made a verbal promise to give her half his money. She was awarded $450 million after a court battle against his sons. She was an actress (of sorts) had her own reality tv show (aired on E4 I think). Terrible.
