In an appalling rant when he was a teenager, Prince Harry allegedly called a French pub manager a "f****** frog", leading the prince to be barred from the pub after the shocking confrontation.
Fresh details of the story have been addressed in royal expert Robert Jobson's new book 'Our King.'
The royal correspondent has exposed behind-the-scenes details about the Royal Family, including the time Harry vented his anger on a night out, reports the Mirror.
In one extract, Harry's drinking habits are discussed after former News of the World royal editor Clive Goodman revealed the Prince's behaviour.
It's claimed that Harry enjoyed crazy boozing sessions at The Rattlebone Inn near King Charles' Highgrove home in Gloucestershire, but one night, he went too far.
Jobson says: "He [Goodman] wrote that Harry, whose father and brother were away from Highgrove at the time, frequented the Rattlebone Inn in Sherston, and got drunk. Harry had then been banned for calling the French manager 'a f***ing frog'."
The pub boss, Franck Ortet, has previously revealed exactly what happened on the night in question.
Franck said he had previously had a close relationship with both William and Harry, who often frequented his pub with their friends, and would have banter with the boys.
However, Harry's jovial manner changed over time and he became increasingly dismissive and rude.
The Frenchman explained that it all came to a head when he got into a verbal altercation with the young royal because he refused to serve him alcohol.
Speaking to the Mail, Franck claimed he asked Harry for ID, but got the reply: "Shut up and get on with your job."
He then said Harry started calling him "Froggie" repeatedly, which he laughed off at first but eventually lost his rag.
Franck explained: "As he carried on calling me names I could see him turning his head to smile at his friends as though he was being really clever. It looked like he was enjoying being the centre of attention.
"I'm sure he thought it was really funny but it annoyed me because everyone was laughing and I felt he was trying to humiliate me. I had to leave to stop myself saying something nasty.
"I went out of the bar to calm down and when I came back they'd gone. I felt offended that he'd made my customers laugh at me."
Franck said he barred Harry from the boozer and he has not seen the Duke since.
He actually praised Harry for being polite and friendly initially but said his behaviour changed as he got older.
While it's never been confirmed, some believe Franck's pub was the one mentioned in Harry's virginity story, as he first had sex in a field outside a boozer.
