The Royal Family's official website made an epic gaffe when announcing the name of Harry and Meghan's newborn.
The exciting news that the Duke and Duchess of Sussex had chosen to call their son Archie Harrison Mountbatten-Windsor was met with delight from fans this afternoon.
The website posted an official statement shortly after the couple shared the happy news on their Instagram page.
However the website announcement contained a very big mistake.
Instead of naming Meghan and Harry as the tot's parents it said Archie was the first child of Kate and William.

Sweet meaning behind Meghan Markle's royal baby name - and it's a touching tribute to Harry
The statement was quickly changed once the error had been spotted - but not before hundreds saw.
It said: "Archie Harrison Mountbatten-Windsor was born at 05:26 on Monday 6 May.
"He is the first child of The Duke and Duchess of Cambridge and is seventh in line to the throne.
"Archie weighed 7lb 3oz and The Duke of Sussex was present for the birth."
It has since been corrected to The Duke and Duchess of Sussex.
Meanwhile, Harry and Meghan have broken with royal convention by making a personal decision not to use a title for their baby boy.

He will simply be known as Master Archie Mountbatten-Windsor.
As the first born son of a duke, Archie could have become Earl of Dumbarton - one of Harry's subsidiary titles - or have been Lord Archie Mountbatten-Windsor.
A source said: "They have chosen not to use a courtesy title."
The decision fits in with Harry and Meghan's desire to give their son as normal a life as possible despite his royal heritage.
Harry, who has admitted he once "wanted out" of the royal family, has spoken in the past of how he was always more comfortable being Captain Wales in the Army than being Prince Harry .

Archie means "genuine", "bold" and "brave", and is German in origin.
Short for Archibald, it is now given as a name in its own right.
Harrison means "son of Harry" so is likely to be a tribute to the duke.
It is English in origin and famous Harrisons include the Star Wars actor Harrison Ford.
Archie is not entitled to be an HRH or a prince due to rules set out more than 100 years ago by George V.
