The world has been on tenterhooks, waiting for the arrival of the royal baby... and he's finally here!
Here is everything we know so far about the British royal family's brand new addition.
At 5.26am on Monday, Meghan Markle and Prince Harry welcomed their first child, a little boy weighing in at 3.26kg.
To announce the arrival, Harry fronted media in Windsor to share the news.
"I'm very excited to announce that Meghan and myself had a baby boy early this morning, a very healthy boy," he said, smiling widely.
"Mother and baby are doing incredibly well. It's been the most amazing experience I can ever possibly imagine.
"But, we're both absolutely thrilled and so grateful to all the love and support from everybody out there... we just wanted to share this with everybody," said Harry.
Despite the pair bucking the trend of a traditional photo op straight out of the delivery suite, Buckingham Palance still upheld tradition, with the Queen displaying a notice of birth on the forecourt of the palace to announce the news.
What's his name?
Harry and Meghan are yet to decide on a name for their newborn son.
"The baby is a little bit overdue, so we've had a little bit of time to think about it but yeah, that's the next bit," he said, when asked about Baby Sussex's all-important moniker.
The next public appearance the family will make is set to be in around two days' time, with the world being able to catch a glimpse of the newest royal - and learn his name and official title - then.
Harry admitted that this is all very new to him, and witnessing the birth of his son was an incredible, life-changing experience.
"How any woman does what they do is beyond comprehension," he said. "I haven't been at many births - this is definitely my first."
"It was amazing, absolutely incredible. As I said, I'm so incredibly proud of my wife and as every father and parent would ever say, your baby is absolutely amazing," he gushed.
The new dad couldn't contain his joy, "But this little thing is absolutely to die for, so I'm just over the moon!"
We best let you get back to your little boy, then, Harry!
