Now that Donald Trump is back on U.S. terra firma (heralded with a flurry of Tweets from the POTUS last night) we can all thankfully put his world trip to bed.
Or so we thought.
On the final leg of the Trump's whistle-stop tour of Saudi Arabia, Israel, Italy and Belgium, Melania was to be found hanging out with the First Ladies and First Man of NATO.
To commemorate what we can only imagine is an incredibly awkward chat between Brigitte Trogneux and Melania about marital age gaps, they assembled for a photo op and The White House Facebook page put up a post about it.
However, those with eagle eyes noticed that Luxembourg's First Man, Gauthier Destenay, was left off the list.
Apparently this was changed, though we can thank Facebook edit history for keeping the evidence.
Gauthier Destenay is an architect and husband to Xavier Bettel (Luxembourg's Prime Minister), and they have apparently been together since 2010 and have been married for the last two years.
Xavier Bettel is the second world leader, after Jóhanna Sigurðardóttir of Iceland, to be part of a same-sex marriage and is the only current world leader.
In 2014 Bettel told the LA Times of his decision to be openly gay in politics, 'I have just one life, and I don't want to hide my life.'
The comment section of The White House's Facebook post is a veritable feast of angry messages.
The comment, 'The omission of the the First Gentleman of Luxembourg name is blatantly disrespectful and just goes to show the level of idiocy of this White House staff' garnered 5.5k likes and, 'Wow. No mention of the Luxembourg spouse? He still exists even if you try to ignore the fact he is a homosexual you dimwit,' got 2.3k.
Likewise, the Twittersphere had something to say about the social media mishap.
Homophobia or social media laziness?
