As the world watched on in anticipation, the royal family announced the birth of the Duke and Duchess of Sussex's baby boy this morning.
The statement from Buckingham Palace confirmed that Queen Elizabeth, Prince Charles, Camilla Parker Bowles, Prince William and Kate Middleton were all informed of the child's arrival.
But there were also three extra names included in the set.
Deviating from the Duke and Duchess of Cambridge's baby announcements, Prince Harry paid tribute to his late mother, Princess Diana, by naming her three siblings ― Lady Jane Fellowes, Lady Sarah McCorquodale and Earl Spencer - in the notice.
The 34-year-old royal has maintained a close relationship with his mother's family, with Fellowes even giving a reading at his wedding last year.
In addition to his joint statement with the royal family, Spencer also tweeted in response to the baby's birth.
"Really very lovely news today - many, many, congratulations! (Good to have another Taurean in the family....)," he wrote.

Harry has continually included tributes to his mother in all his big milestones; such as their engagement when Harry included two diamonds from Diana's collection in his wife's engagement ring and at their wedding when the hymn "Guide Me, O Thy Great Redeemer" from the much loved Princess' funeral was played.
Back when the couple announced their engagement, Harry said his mother would've been "over the moon, jumping up and down, so excited for me, but then would've also probably been best friends with Meghan."
The new royal baby now becomes the seventh in line to the throne, behind his father; three cousins, Prince George, 5, Princess Charlotte, 4, and Prince Louis, who just celebrated his first birthday; Harry's brother, Prince William; and the baby's grandfather, Prince Charles.
We have no doubt that Princess Diana is beaming with pride today.
