Wait, did Prince George let the royal baby name slip months ago?

Prince Harry and Meghan Markle welcomed their first child together earlier this week, announcing on their Sussex Royal Instagram page that the royal baby had officially arrived and that it was a boy.

‘We are pleased to announce that Their Royal Highnesses The Duke and Duchess of Sussex welcomed their firstborn child in the early morning on May 6th, 2019. Their Royal Highnesses’ son weighs 7lbs. 3oz,’ the couple announced.

But it was the royal baby name of choice that made the most noise, with Harry and Meghan confirming that they had chosen the moniker, Archie, or Archie Harrison Mountbatten-Windsor in full.

‘The Duke and Duchess of Sussex are pleased to announce they have named their first born child: Archie Harrison Mountbatten-Windsor’, the couple announced in an official statement alongside a sweet photograph of the Queen meeting the newborn. ‘This afternoon Their Royal Highnesses introduced Her Majesty The Queen to her eighth great-grandchild at Windsor Castle. The Duke of Edinburgh and The Duchess’ mother were also present for this special occasion.’

But while the name of choice surprised the world, eagle eyed royal fans pointed out that there was actually a big hint last year - from Prince George.

Yes, the miniature royal dropped the name last year when he ran into a dog walker, reportedly passing the name off as his own.

According to The Sun, a dog walker was approached by Prince George in Berkshire, where he was playing with his grandma, Carole Middleton and Princess Charlotte.

‘I was asked by a police minder not to take a photo of the children, which I didn’t, but George started stroking my dog,’ explained the dog walker who has chosen to remain unnamed. ‘Just to be friendly I engaged in a bit of small talk and I asked George what his name was, even though obviously I knew it.’

She continued: ‘To my astonishment he said “I’m called Archie” with a big smile on his face. I don’t know why he calls himself Archie but kids often play with their names and I think it’s lovely.’

While some have speculated that Harry and Meghan may have grown a fondness for the name from George’s use of it, others believe that Baby Sussex’s name was chosen last year and Prince George accidentally let it slip!

Either way, surely there's enough room for two Archies in the royal family!
