He's the cutest little thing.

Prince George has been getting quite the reputation for being a cheeky little monkey over the past year or so, and we absolutely love when he's that little bit more mischievous at royal occasions. George celebrated his 5th birthday this weekend, and to celebrate Kensington Palace released a new official photo of the birthday boy. Taking to Twitter, the Palace wrote: "The Duke and Duchess of Cambridge are very pleased to share a new photograph of Prince George to mark his fifth birthday – thank you everyone for your lovely messages." And shared this picture:

Only last week, the royal family released photos of Prince Louis's christening. Prince Louis was christened two weeks ago and the royal event was the source of much media attention. His parents, the Duke and Duchess of Cambridge, his siblings, Prince George and Princess Charlotte, his grandparents, the Prince of Wales and the Duchess of Cornwall were in attendance among others. And while many photos have been shared online of the big day, Kensington Palace released the official photos, which were absolutely gorgeous:

The Duke and Duchess of Cambridge have released four official photographs to mark the christening of Prince Louis on Monday 9th July.

The photographs were taken by Matt Holyoak at Clarence House, following Prince Louis's christening. pic.twitter.com/v6mN6QDgrr — Kensington Palace (@KensingtonRoyal) July 15, 2018
