Norfolk boy Prince George celebrates his fourth birthday today.
An official picture has been released to mark the occasion, which shows the young future king looking incredibly happy.
The Prince spent the run-up to his big day on an official tour of Poland and Germany with his parents, the Duke and Duchess of Cambridge.
And the coming months look set to be just as eventful, as William and Kate's eldest child is scheduled to start school in September.
George is joining private day school Thomas's Battersea where fees cost £17,604 a year.
The Duchess has said previously, she is not sure George 'has any idea what's going to hit him' as he begins full-time education.
Prince George Alexander Louis of Cambridge was born on July 22 2013 at St Mary's Hospital in London, weighing 8lbs 6oz.
He made his public debut one day later on the steps of the hospital, cradled in his parents' arms.
