His Royal Highness Prince George AKA our reigning sweetie pie is about to become a big brother once again (with his mum, Duchess Catherine, in labour as we type!).
Duchess Catherine and Prince William's eldest first graced us with his cheeky presence all the way back in 2013 on July 22.
We honestly can't believe the royal tyke is now hitting the new milestone.
And it's not the only one, George will start big school in September!
The (nearly) birthday boy will attend Thomas's Battersea School in London.
"Their Royal Highnesses are delighted to have found a school where they are confident George will have a happy and successful start to his education," the palace said in a statement.
Before the third-in-line-to-the-throne begins the next very exciting chapter in his life, we celebrate one of our favourite things about him - the fact that Prince George and his cherub cheeks are ridiculously endearing...
And he's his daddy's complete doppelganger!
Scroll through and relive the VERY many moments you blinked and thought Prince George was actually his dad Prince William
Royal watchers across all the kingdoms nearly fainted with sheer delight when young George made his Buckingham Palace balcony debut back in 2015.
At the time, Georgie had just embarked on the huge role of becoming Princess Charlotte's big brother, after his mum welcomed her a couple of weeks prior.
With the new responsibility on his should, the young Prince channeled his father's we;;-respected calm nature as he waved to the kingdom below.
But George was still a toddler, so we were treated to the casual hilarious outburst, something we'd seen from Prince Harry many moons ago!
While His Royal Cuteness is always compared to his father, the three-year-old has certainly inherited a thing or two from his mum, Duchess Catherine.
Over the years we've seen him channel her sense of adventure and of course her infectious laugh!
The one thing we can always rely on George for is him always giving us good face.
Seriously, the future king never holds back how he's feeling and we're guessing he's picked up a thing or two from his Gan-Gan Queen Elizabeth.
Both William and George just adore spend time with their mum.
For the sweet moments they've shared with the public, it is clear the bond is something they'll cherish for the rest of their days.

William describes his son as a cheeky monkey and we see George as a mirror of his incredible father.
Whether he's playing with toys, or going to church with the family - avid royal well wishers love seeing the young family out and about.
