Dressed in a black suit with a grey tie, Destenay stood among the world leader's glamorous spouses.

He stood directly behind Mrs Trump and the none-too-pleased Emine Erdogan, the devoutly Muslim wife of Tayyip Erdogan, President of Turkey.

Unlike some of the women, Destenay opted to stay in the same suit-tie combination he had worn earlier in the day when he was given a tour of the Magritte Museum, which is devoted to the works of Belgian surrealist painter René Magritte.

He was joined by other NATO spouses including Mrs Trump, Mrs Erdogan, French First Lady Brigitte Macron and Belgian Prime Minister Charles Michel's partner, Amelie Derbaudrenghien.

Destenay was pictured enjoying a friendly chat with the French and US first ladies at the museum, which is famed for works like the 1964 'self-portrait' of a bowler-hatted man whose face is hidden by an apple.

His husband became the first gay EU leader to enter into a same-sex union when the couple married in a low key ceremony two years ago.

Their wedding came just months after Luxembourg legalized same-sex marriage.
