Princess Kate's brother, James Middleton, made a heart warming gesture on Wednesday to mark his nephew, Prince Louis's seventh birthday.

The Princess of Wales and Prince William's youngest child celebrated his seventh birthday, and the royals made sure to mark it in a special way. Hours after posting a new portrait of the young prince in Norfolk, Kensington Palace uploaded a new video on social media showing a glimpse of the photoshoot he had to mark his special day. Louis was shown posing for the camera in the sunshine and running up close to the lens. He was also seen pointing and saying "I can jump down from here" before walking along and making a large jump off a log.

The video, accompanied by the message "Seven today!", was filmed by Kensington Palace's in-house social media team, and was set to gentle music and filmed in the style of an archive home movie, similar to the technique used in Kate's video last year announcing the end of her chemotherapy treatment.

Royal fans could not contain their excitement and nor did Louis's uncle, as he liked the post on social media.

Earlier, the Prince and Princess of Wales also shared an image from the session to mark their youngest son's big day on Wednesday.

It was accompanied by the message: "Wishing Prince Louis a very Happy 7th Birthday!" followed by a cake emoji.

Louis is pictured sitting on a tree trunk, smiling and showing a gap for his two front teeth, in the photo posted on William and Kate's social media accounts.

Louis, who is known for his cheeky antics on the Palace balcony, is fourth in line to the throne and a grandson of the King.

He was born on St George's Day, April 23, in 2018, at the private Lindo Wing of St Mary's Hospital in Paddington, London, weighing 8lb 7oz.
