It's over! Athina Onassis and her husband have officially announced their separation amid shocking new reports that he was cheating on the billionaire French-Greek heiress.
Onassis, the 31-year-old granddaughter of Aristotle Onassis, the Greek shipping magnate who was married to Jackie Kennedy, and Alvaro "Doda" de Miranda Neto released a statement this week after buzz began last month.
"Anyone who has been through a separation knows how painful it is," his rep said in a statement to People.
"Doda Miranda and Athina Onassis were married for eleven years and on this journey they shared a life, a love for horses, for sports and for family."
But People claimed his alleged cheating was the cause of the split.
"When Athina learned of Doda's cheating in March, she left Wellington, Florida, and has not returned," a source told the magazine. "She initially fled to Belgium."
However, his rep denied the allegations, saying, "They maintain a cordial relationship and would like to be able to go through this painful moment with the maximum privacy and respect and not be the victims of any more defamation and dishonest news."
