Donald Trump's comments following the leaked sunbathing images of Princess Catherine reportedly resulted in "torrents of profanity" from her husband and father-in-law.
In one of the most talked-about scandals regarding the Royal Family in the last 20 years, the then-Kate Middleton was snapped by photographers as she sunbathed topless on the private grounds of a French chateau back in 2012.
These images were later published by the French magazine Closer and the Italian gossip magazine Chi, causing an uproar in the media.
An analysis of the images by The Times later suggested that the images were potentially taken around half a kilometer away - a distance that would require an 800mm or a 1000mm lens.
Additionally, BBC News reported at the time that Prince William and Princess Catherine took legal action against Closer magazine, with French courts eventually prohibiting the magazine from re-publishing or distributing photographs in the country.
Five years later, and the publication was fined €100,000 for the privacy intrusion, with editor Laurence Pieau and owner Ernesto Mauri each being fined an additional €45,000.
As expected, the photos also became a talking point on social media, with businessmen and future President of the United States Donald Trump tweeting, per Newsweek: "Kate Middleton is great – but she shouldn't be sunbathing in the nude – only herself to blame."
Trump reportedly added: "Who wouldn't take Kate's picture and make lots of money if she does the nude sunbathing thing. Come on Kate!"
Now, Royal expert and author Christopher Andersen has written about the alleged response to Trump's comments in his new book, The King: The Life of Charles III.
Detailing the alleged response from the Royal Family, the New York Times best selling author writes: "Trump's criticism of Kate resulted in what one Clarence House butler referred to as 'torrents of profanity' from both Prince Charles and his sons."
Per Newsweek, Anderson goes on to claim that tensions boiled over to the point where the UK Royal Family attempted to "discourage" a planned visit by Donald Trump to the UK back in 2017.
The alleged visit never went ahead, but Trump did make a three-day state visit to Britain in June of 2019 - during his time as POTUS.
The King: The Life of Charles III is set to be released on December 8.
