Adorable Prince Louis plays with grandfather Prince Charles in new photos – see album

Prince Charles celebrated his landmark 70th birthday last week with the release of some beautiful family portraits, but it was the youngest members of his brood who managed to steal the show. The Prince of Wales was pictured with his sons Prince William and Prince Harry, his daughters-in-law Kate and Meghan, his wife the Duchess of Cornwall and the tiniest members of his family – Prince George, Prince Louis and Princess Charlotte – in the photos featured exclusively in The Sunday Times magazine.

The bond between Grandpa Wales and the little Cambridges was clear to see. In one photo, Louis, who was four months old at the time, affectionately grabbed his granddad's face. His mother Kate laughed as she held onto her baby boy, while her older son George bounced on Charles' lap. Charlotte, meanwhile, was the picture of cuteness sitting next to Camilla.

In the Sunday Times interview, renowned photographer Chris Jackson, who took the photos, noted that – surrounded by his family – Charles was at his happiest. Let's take a look at the full album…

One particularly heartwarming photo showed Grandpa Wales with baby Louis. Chris Jackson said: "It was lovely chaos with the children. He is a very hands-on grandfather. He was holding hands with George and Charlotte, and bouncing Louis up and down for a long time. George was very happy on the Prince's knee. They have a great relationship that's a little more established, as George is a bit older."

The official photographs were taken on 5 September in the gardens of Clarence House. Chris – the man behind Prince George's fifth birthday portraits and the Cambridges' official Christmas photo last year – revealed that this light-hearted snap was perhaps his favourite one of all time.

Until now, the public had only seen a few photos of Prince William and Kate's third child, so they were no doubt thrilled when the portraits were released. Little Louis flashed a gummy smile at the camera, looking adorable in a £72 blue-and-white outfit by Spanish clothing company La Coqueta.

The photos were taken to mark His Royal Highness's 70th birthday last Wednesday and showed Charles at work and at home.

In one photo, Charles was flanked by his two handsome sons who looked dapper in uniform. The pictures, which were also turned into commemorative stamps, were taken at the 100th birthday celebrations of the Royal Air Force in July.
