Athina Onassis

Athina Onassis is the last living descendant of controversial Greek millionaire Aristotle Onassis, making her style icon Jacqueline Kennedy Onassis’ granddaughter by marriage. She was once projected to be worth $5 billion, having received $800 million in inheritance on her 18th birthday.In recent years, however, the heiress appears to have fallen on hard times, and there is conjecture that her fortune is rapidly shrinking due to the expenses of her luxurious lifestyle and her reported $100 million divorce payout to her philandering ex-husband.Even the media in her home nation of Greece is speculating on the heiresses’ financial situation, with one headline stating “Athina Onassis May Not Be Billionaires Anymore!” Ouch!
