At the NATO summit currently being staged in Brussels, the spouses of some of the world’s most powerful leaders posed for a photograph.
Among them was FLOTUS Melania Trump, Queen Mathilde of Belgium and France’s new First Lady Brigitte Macron.
But everyone is talking about Luxembourg’s First Gentleman Gauthier Destenay.

He's not the only male NATO spouse, of course - German Chancellor Angela Merkel's famously publicity-shy husband, Joachim Sauer, was absent this year.
But the Belgian architect is one-half of the world's only openly gay first couple.
Gestenay has been married to Luxembourg's Prime Minister Xavier Bettel since 2015, the year same-sex marriage was legalised in the tiny European nation.
