Athina Onassis – $ 5 Billion

Athina Onassis is the last living descendant of Aristotle Onassis, who was a Greek billionaire and husband of the former first lady of the United States, Jaqueline Kennedy. For her 18th birthday, Athina was given $800 million which grew to around $5 billion.

She is known for her lavish lifestyle and combining this with her uneventful divorce with Olympic athlete, Álvaro de Miranda Neto, her net worth may have decreased. Of course, she won’t be needing a bankruptcy attorney since the decrease is probably just a billion. This means that she’s still a multi-billionaire who can fund her extravagant expenditures.
