Donald Trump has caused a stir after referring to Prince Charles 'the Prince of Whales' on Twitter.
Trump was responding to an interview he gave to ABC on Wednesday night, where he said he wouldn't necessarily alert the FBI if a foreign Government offered him information on a presidential rival in the 2020 elections.
The US President wrote on Twitter: "I meet and talk to "foreign governments" every day.
"I just met with the Queen of England (UK), the Prince of Whales, the PM of the United Kingdom, the PM of Ireland, the President of France and the President of Poland."
We talked about "Everything!" 'Should I immediately call the FBI about these calls and meetings? How ridiculous!".
Minutes later, the president changed the spelling to correctly refer to the future British monarch by his correct title, the 'Prince of Wales'.
One Twitter user wrote: "Too late. Internet is forever. PRINCE OF WHALES!"
But another jumped to his defence, saying: "Mr. President don't worry about these fools.
"They hate you so much they're inventing crimes nobody has ever heard about!
"They grandstand on xenophobia and then they say talking to foreigners is a crime. These people are sick!"
One Twitter user simply said: "The Internet remembers things better than you do."
The error comes despite Mr Trump's state visit to the UK this month, where he was invited as a guest of the Queen to a state banquet at Buckingham Palace.
Mr Trump spent time with Prince Charles during a ceremonial Guard welcome, as well as posing for photos and talking extensively with the Prince of 'Wales'.
