While Prince Harry might be all smiles, nods and politeness when he's doing official Royal business, it's a case of 'no more Mr Nice Guy' when he steps onto the polo pitch. That's according to an Aussie player who competed against the 33-year-old in 2014.
Queenslander Beau Skerrett has seen his fair share of horses and polo sticks after playing it for 12 years. But while there's often a bit of argy-bargy in any type of sport, Beau says Prince Harry went a bit over the top.
The Royal's antic apparently got so out of hand that the Aussie player had to tell him to 'fuck off' while they were playing at Sir Andrew Lloyd Webber's place in the UK. But these weren't the only choice words he had to say about the fifth in line to the throne.
He told the Courier-Mail: "Harry loses his cool [on the field]. He is a spoiled brat. It got to the point where I couldn't send anyone off but something had to be said because he was just getting a bit serious.
"He didn't take it too well. I think I'm the only guy who ever told him to fuck off in front of a crowd that pay £5,000 ($6,663) to shake his hand.
"It was very funny and William actually apologised for him."
Beau added that this mini-feud was over as soon as they game finished, and they went back to being cordial mates. He said Harry was better than his older brother, but William is the 'perfect bloke'.
Prince Harry has probably been playing polo ever since he could stay on a horse with a kid's stick. He excelled at the sport when he was at Eton, but has regularly used it as a way of raising tons of money for charities and organisations.
Considering entry to some of these matches is more than some people get paid a month, it's nice to hear that he's funnelling some of that cash to a good cause.
But it's not the only sport that he enjoys, with rugby union, skiing and motocross also being keen interests.
There is plenty of speculation that Harry is on the verge of proposing to his girlfriend Megan Markle after a little more than a year of dating. The bookies have suspended betting on the matter and the Daily Mail reports the BBC is getting 'primed' for the engagement announcement.
