Destenay is from Belgian Luxembourg and has been working as an associate architect at Belgian-Luxembourg firm A3 Architecture since 2013. He graduated with a degree in architecture from the University of Liège in 2003.[1][2][3]
Destenay asked for Bettel's hand in marriage in August 2014. They were married on 15 May 2015 in a private ceremony officiated by Luxembourg city mayorLydie Polfer in the presence of around 250 guests. Bettel became the first European Union head of government to marry a same-sex partner.[1] The wedding was also attended by Elio Di Rupo, the former Belgian Prime Minister who was the European Union's first openly gay head of government. The ceremony was followed by a reception for 500 guests at the Cercle-Cité.[4][5][6]
Destenay gained attention on social media when he appeared as the only male spouse in a group portrait of world leaders' spouses and partners at the 2017 NATO summit. Destenay's name was omitted from the caption of a Facebook photo posted by the White House, even though all the other spouses were correctly labeled. The post was subsequently edited after it led to criticism and accusations of homophobia.[7][8][9]
