The whole world is celebrating the arrival of Prince Harry and Duchess Meghan's son, but the new doting dad himself is just head over heels.
The sixth in line to the throne has made no secret that he loves kids and has wanted to be a father for years so when he stepped out to confirm the arrival of his new baby boy, it was pretty clear that he was over the moon.
Watch the moment in the player above!
"It's been the most amazing experience I could ever have possibly imagined," a delighted Harry told the press on Monday shortly after Meghan's birth.
"We're both absolutely thrilled and so grateful for all the love and support from everybody out there, it's been amazing so we just wanted to share this with everybody."
"Every father and parent will say your baby is absolutely amazing but this little thing is absolutely to die for. I'm over the moon."
Now that Baby Sussex is finally here, we take a look back at everything Prince Harry said about his son before he was even born. Hold onto your ovaries, things are about to get super cute.
Who could forget when the Duke and Duchess of Sussex revealed their exciting news to the world on day one of their royal tour of Australia?
Speaking at Admiralty House, Prince Harry told the press, "We're both delighted to be here and really impressed to see you serving beer and tea at an afternoon reception, in true Aussie style. And we also genuinely couldn't think of a better place to announce the upcoming baby, whether it's a boy or a girl, so thank you very, very much," he shared.
The proud new royal dad has visited Australia on numerous occasions as a single man, but on his first trip with Duchess Meghan, he thanked the audience at the Invictus Games Opening Ceremony for their support.
"First of all, thank you for the welcome you have given Meghan and I over the last few days. I have been so proud to be able to introduce my wife to you and we have been so happy to be able to celebrate the personal joy of our newest addition with you all," Harry said, followed by massive cheers from the crowd.
Like many modern parents, Harry and Meghan wanted their baby's gender to be a surprise. Even though we now know that Baby Sussex is a boy, they've already reportedly designed their gender-neutral nursery at Frogmore Cottage.
However, the Duke of Sussex revealed his preference at the road cycling event at the Sydney Invictus Games last year when someone in the crowd called out to the red-headed royal, "Congratulations, I hope it's a girl!"
To this, Harry replied, "So do I!"
At Fiji University, one boy also told the duke, "I'm predicting it's going to be a boy," while Harry responded, "Everyone is predicting it's going to be a girl."
Baby Sussex may be a boy but we have a feeling Prince Harry is pretty delighted anyway!

Royal reporter Carolyn Durand says that as he and his wife greeted well-wishers along the Viaduct Harbour in Auckland, Prince Harry told one fan that he was "over the moon" about becoming a dad.
When the woman said it's a lot of hard work, he responded, "Oh, I know – I'm ready!"
We can just imagine Harry practising his nappy changing skills at Frogmore Cottage!
When Harry delivered a slightly less formal speech in the Abel Tasman during the couple's tour of New Zealand, he revealed a sweet nickname for the unborn bub.
As he thanked their accompanying guests during the engagement, the prince said, "From myself and my wife and our little bump, we are so grateful to be here. We bring blessing from my grandmother the Queen and our family."
Kensington Palace also posted an official message from Prince Harry thanking New Zealand for their hospitality during the royal tour. The message was accompanied by a gorgeous photo of Meghan cradling her bump in a beautiful forest called Redwoods Tree Walk in Rotorua, snapped by Harry himself.
Prince Harry may have those new dad nerves, but he certainly hasn't shown it.
The sixth in line to the throne told ABC TV that he was feeling "fantastic" about becoming a dad, but said that it will also bring "new responsibilities" along with a "new third of our lives."
