Leona Helmsley

When the real estate tycoon dubbed the “Queen of Mean” died in 2007, she had cut two grandchildren out of her will and left a £9.3million fund to her Maltese dog Trouble.

She also left millions to her brother Alvin Rosenthal, who was appointed as Trouble’s caretaker.

She wanted her dog to later be buried along with her in the family mausoleum but the cemetery board would not allow non-human remains on the property.
