I can’t believe it’s been 9 whole years since we all stared at a door for a month waiting for the birth of Prince William and The Duchess of Cambridge’s first child. So much has changed in those 9 years! Today, July 22, marks Prince George‘s 9th birthday.

To mark George’s 9th birthday, Kensington Palace released a new photo of the birthday boy, taken by his mother while on holiday in the UK earlier in July.
