After royal fans waited in anticipation following the birth of Prince Harry and Duchess Meghan's little bundle of joy, Baby Sussex's name was finally revealed to be Archie Harrison Mountbatten-Windsor.
But if you had a strange sense of déjà vu, there could be a reason why.
We've heard this moniker before – and things may be about to get a little awkward.
Sure, no one in the Royal Family is officially named Archie. But the choice may be a slight bone of contention for Prince George.
Apparently, the five-year-old recently claimed that his nickname is Archie.
According to The Sun in January, a dogwalker was approached by William and Kate's eldest son near grandparent's Carole and Michael Middleton's home in Berkshire.
The dogwalker was left "astonished" when Prince George told her his name was "Archie."

"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," she told the UK outlet.
"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."
"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."
At the time, theories were rampant about why George decided to give himself the pseudonym.
One thought is that it could be George's code name for security purposes.
His father William and uncle Harry also reportedly had code names in their early twenties, and their inner circle referred to them as "Steve" and "Spike" respectively.
Of course, with no confirmation that George is actually called "Archie" by those around him, he may have just been trying to pull the wool over the woman's eyes or possibly just made up the nickname on the spot.
According to royal insiders, the third in line to the throne is actually nicknamed PG by his schoolmates - the initials for Prince George.
Either way, hopefully the "stolen" nickname doesn't reignite any tension between The Cambridges and The Sussexes, whose relationship has been strained for some time.
