Prince Harry and Meghan Markle told the world that their little boy Archie had been born on Instagram , and the new dad made an excited announcement near their Windsor home.
But before they shared the happy news with fans across the globe, they first had to tell their nearest and dearest about the little arrival.
And while you might imagine the royals have a fancy way to make big announcements, it was actually very, very normal.
According to Mike Tindall, who is married to Harry's cousin Zara, the Duke simply put a message in the royal cousins WhatsApp group.
As well as the Tindalls, we imagine Princesses Beatrice and Eugenie are also in the group as Harry and William are very close with them.

"Lena and obviously Louis are similar ages and Mia's sort of in between Charlotte and George, and then you've got Peter's children Savannah and Isla who are just a little bit older.
"Harry, he's busy, but he loves playing with them all and he'll be a good dad."
