World leaders from across North America and Europe are currently in Brussels, Belgium, for a NATO conference. And with them came their spouses, who assembled at Royal Castle of Laeken on Thursday evening for a photo opportunity before a dinner especially for spouses in the evening.
But one attendee stole the show, and it wasn't Melania Trump. It was Gauthier Destenay, the husband of openly gay Prime Minister Xavier Bettel of Luxembourg.
Bettel became the first openly gay European leader in 2013, and married Destenay two years ago, just a few months after he led efforts to legalize same-sex marriage in the country. Bettel is the third openly gay head of government in modern history, and the only one currently serving.
So it's unsurprising that social media got pretty excited about the moment.
This is a big step forward.
