In 2015, Destenay married Luxembourg's Prime Minister Xavier Bettel, who is currently the world's only openly gay state leader and third openly gay head of government in history. Destenay, an architect, is actually from Belgium.
The two had entered a civil partnership in 2010 and wed months after Luxembourg legalized same-sex marriage. Bettel is the first European Union state leader to wed a person of the same sex.
Bettel, a liberal, became prime minister of Luxenbourg in 2013 after more than 30 years of conservative rule.
