Buckingham Palace marked the tot's milestone birthday with the release of new pictures showing him enjoying a day out at the Natural History Museum with doting parents Prince William and Kate, the Duke and Duchess of Cambridge.
It's hard to believe that just a year ago we were all staring at those double doors of the Lindo Wing at St. Mary's Hospital in Paddington, London waiting for news of the royal baby's arrival…
Little George was born on Monday, 22 July at 4.24pm, weighing 8lbs 6oz.
He is third in line to the throne after his grandfather Prince Charles and his father Prince William.
William and wife Kate Middleton chose not to learn their baby's sex before his arrival meaning the arrival of a little boy was a complete surprise.
Buckingham Palace announced the birth via a press release – which was a twist from the original plans of announcing via the public easel. At the time, it was suggested the palace wanted to stop the birth being leaked before an official announcement was made.
After the press release was issue, the traditional easel announcement took place. Medical staff signed a birth announcement then a royal aide (and police escort) carried it to Buckingham Palace where it was attached to an easel in the forecourt of the estate.
Hundreds of media, photographers and royal enthusiasts had camped outside the hospital and palace awaiting news of the arrival. When it came, there were loud cheers and whistles.
Media were actually camping outside the hospital for a whopping two weeks waiting for the moment Kate, 31, would go into labour and the world would have a new prince.
And it was the height of summer and baking hot.
Celebrations took place all over London, with the BT Tower broadcasting a special 'it's a boy' message and the London Eye lighting up in the colours of the Union Jack. The Buckingham Palace guards marked the arrival the following day while Changing The Guard.
Kate arrived at the Lindo Wing around 6am the morning of Prince George's birth, with the palace confirming she was in labour a couple of hours later.
After the birth, we saw Prince Charles and Camilla, the Duchess of Cornwall, arriving at St. Mary's to visit the baby, and Kate's parents Carole and Michael Middleton.
The following day, we got our first glimpse of the baby when Kate and William exited the Lindo Wing looking proud as punch just after 7pm.
Kate was wearing that now-famous blue polka dot dress, while William was casually clad in dark trousers and a shirt. We watched as Kate held the baby, then transferred him to William while photographers looked on.
Then, they returned to the hospital, emerging with Prince George in a car seat. Watched by the world's media, William was seen loading his son into a car before driving the baby and his wife home for the first time.
William, Kate and George stayed overnight at Kensington Palace, where they were visited the next day by The Queen and Prince Harry.
Then, they packed up their things and headed off to Kate's parents' home in Berkshire where they retreated from the limelight for a while to spend precious time with their newborn.
