Harry arrived at the Sportcampus Zuiderpark in The Hague as part of celebrations to mark the official launch of the 2020 Invictus Games in the Netherlands.
The new father's itinerary will see him meet with competitors and their families, and watch exhibition matches of some of the sports wounded veterans will compete in over the course of the competition, which Harry founded in 2014.
Still on a high from Archie's birth, Harry smiled at the crowd, but also showed signs of a new dad.
Yes, Harry. We see those tired eyes!
According to The Mirror, fans at the sports centre cried, "Marry me, Harry!" as he stepped out of the car.
He was met by Princess Margriet and chairman of the games Mart de Kruif.
Less than 24-hours earlier, he was presenting Master Archie to the world for the very first time!
Of motherhood, Meghan told the world at the highly-anticipated reveal, "It's magic, it's pretty amazing. I have the two best guys in the world so I'm really happy."
While Harry joked that they didn't know where their son's "sweetest temperament" came from.
