Prince George’s fifth birthday has been celebrated with the release of a new official picture.

George Alexander Louis of Cambridge was born in the private Lindo Wing at St Mary’s Hospital, Paddington, at 4.24PM on July 22, 2013.

Prince William and Kate Middleton’s eldest child was photographed in the garden of Clarence House.

The picture was taken after the christening of Prince Louis.

Photographer Matt Porteous had also taken private pictures for Prince William and Kate Middleton at the christening of two-month-old Louis earlier this month.

Prince George was last seen, alongside his siblings and parents, at the christening in The Chapel Royal at St James’s Palace. It was the first time the family-of-five had been seen together.

Prince George’s Fourth Birthday Marked with New Official Portrait

Prince George’s Third Birthday: Kate Middleton and Prince William Release Four Official Pictures

A great-grandson of the Queen, the little prince is third in line to the throne.

George has made a number of public appearances in the past 12 months, including on the balcony at Buckingham Palace for the Queen’s official birthday celebrations in June.

He was seen having fun with Savannah Phillips, the 7-year-old daughter of Prince William’s cousin Peter and his wife Autumn Phillips, who jokingly told him to shush and put her hand over his mouth.

Prince George was also a page boy at the wedding of his uncle Prince Harry to Meghan Markle in May.

He recently completed his first year at school, Thomas’s Battersea in south London, where he played a sheep in the nativity play at Christmas.

The prince is said to love helicopters and flying – perhaps taking after his father, who worked as an RAF search and rescue helicopter pilot.

To mark Prince George’s birthday, a new £5 coin has been issued by the Royal Mint, showing St George and the Dragon on its reverse.
