Athina Onassis

Onassis was born at American Hospital of Paris in Neuilly-sur-Seine, France, to Christina Onassis (1950–1988) and her fourth husband, Thierry Roussel, a French pharmaceutical heir.

She was baptized on the island of Skorpios, owned by the Onassis family at the time.

The remaining 45% of Aristotle's fortune (minus $26 million settled upon Jacqueline Kennedy Onassis) was left to the Alexander S. Onassis Foundation, established in honor of Alexander Onassis, Athina's late uncle, who had died in 1973.

When Athina Onassis was seven years old, The New York Times cited a report from the Associated Press, naming Onassis one of the year's new billionaires, and even though she is often credited as a "billionaire heiress" throughout the media, the true extent of her wealth remains unknown.

There have been several estimates of her inheritance, including the island of Skorpios, which was later sold to trusts connected with Ekaterina Rybolovleva, with some accounts claiming that Onassis's net worth is less than $1 billion.

Rybolovleva bought the island for $153 million.

Onassis' mother Christina never trusted Thierry Roussel completely, which led the family to arrange for a board of administrators to control the family's money until Athina came of age.

Her parents were married from 1984 to 1987.

They divorced after Roussel had two children with his mistress, Swedish model Marianne "Gaby" Landhage.

Athina Hélène Onassis (Αθηνά Ωνάση; born Athina Hélène Roussel (Αθηνά Ρουσσέλ), 29 January 1985 ) is a French-Greek heiress and equestrian, the only surviving descendant of Greek shipping magnate Aristotle Onassis, and the only child of Aristotle's daughter Christina Onassis.

She makes rare public appearances.

Onassis has three half-siblings via her father's relationship with Landhage: Erik Christopher Roussel (born July 1985), Sandrine Roussel (born May 1987), and Johanna Roussel (born July 1991).

Onassis is a competitive show jumper in select events of the Global Champions Tour.

Christina Onassis died of pulmonary edema in November 1988, when Athina was three years old.

After her mother's death, she was raised by Roussel and Landhage, whom Roussel later married.

For her early education, Onassis attended a school in Lussy-sur-Morges, Switzerland, where the Roussels lived.

She began riding as a child, and finished second in an event in Jerez, Spain in 2001.

She later chose to compete as a Greek citizen for the Avlona Riding Club in Athens, under the name Athina Onassis.

Following a preparatory course in Brussels, Belgium, she passed her baccalauréat exam in the summer of 2003.

Onassis began dating Brazilian professional showjumper and two-time Olympic medalist Álvaro de Miranda Neto in March 2003 and moved to São Paulo.

She bought a 10600 sqft duplex overlooking Ibirapuera Park for $8.6 million.

Miranda and Onassis were married on 3 December 2005.

Most guests attending the lavish ceremony were Brazilian VIPs or friends from the equestrian community.

The bride's father and stepmother were not present.

The couple reportedly asked for their guests to donate to charity.

Following her marriage, Onassis assumed the name of Athina Onassis.

The Athina Onassis International Horse Show, a show jumping competition, was established in 2007 in São Paulo and moved to Rio de Janeiro in 2009.

In November 2012, Onassis suffered a spinal injury in a fall from her horse, but represented Greece in the 2013 European Show Jumping Championships and the 2014 World Championships.

Onassis is a patroness of the Global Champions Tour.

In 2014, the competition moved to Pampelonne beach in Saint-Tropez, France.

Onassis and her former husband were joint owners of AD Sport Horses, a horse breeding and training business based in Fleurus, Belgium.

In February 2014, Onassis paid $12 million for a 5.6 acre estate and barn in Wellington, Florida.

In 2016, the couple legally separated, following Miranda's alleged infidelity.

Divorce negotiations began almost immediately, with Onassis hiring high-profile divorce lawyer Robert Stephan Cohen.

The divorce caused complicated legal issues in the courts of Antwerp, Belgium, where Onassis had been living.

Miranda challenged the prenuptial agreement and demanded alimony payments, and there were custody disputes over jointly owned horses.

She sold the estate in April 2017 for $12.75 million.

The divorce was settled in November 2017.

After her divorce, she moved to Greece.

Athina Onassis is the sole heiress of Christina Onassis, who inherited 55% of Aristotle Onassis's fortune.
