The 31-year-old and Álvaro, 43, first met at a riding school in Belgium and tied the knot back in 2005 in a lavish ceremony held in São Paulo. For her nuptials, Athina donned a Valentino gown. The couple share no children together, though Álvaro has a daughter from a previous relationship.

Amid reports of infidelity, the gold medalist's rep told People that the former couple "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."

Athina is the granddaughter of Greek shipping magnet Aristotle Onassis — who was Jacqueline Kennedy’s second husband. Like her ex, the heiress is also an accomplished equestrian.
