Although wee Louis appeared to have slept in Catherine, Duchess of Cambridge's arms throughout the majority of his 40-minute christening service, he's wide awake and oh-so-adorable in the official christening portraits that were released by Kensington Palace on Sunday.

Royal photographer Matt Holyoak was picked to capture the precious moments between the family.

However, just because the Queen couldn't physically attend, doesn't mean she was left out of the event, as the photos, taken by Matt Holyoak, show a painting of the Queen on the wall behind the happy family, just in shot in the background. I only hope I have captured some of that joy in my photographs, ' Holyoak said in an official statement.

It was the first time the five members of the family have been photographed together.

After nearly a week of waiting, Prince Louis's official christening photos are finally here.

The snaps were taken at Clarence House, where Prince Charles and Camilla Parker Bowles live, after the baptism, which took place on 9 July. His two older siblings are Prince George (22 July 2013) and Princess Charlotte (2 May 2015).

While Charlotte has her attention exclusively on her baby brother, George shows a rare playful side and flashes a huge grin to photographer Matt Holyoak.

Also in attendance were both William's father, Charles, the prince of Wales and stepmother Camilla, the duchess of Cornwall. Queen Elizabeth II and her husband Prince Philip didn't attend. Of course, we're enamoured with this one with Meghan and Harry, but what really steals the show is Prince George's cheeky grin.

The Prince's godparents were also announced the morning of his christening as Nicholas van Cutsem, Guy Pelly, Harry Aubrey-Fletcher, Lady Laura Meade, Robert Carter and Lucy Middleton.

The fifth-in-line to the throne looked peaceful in Kate's arms in all four portraits, while the typically shy and reserved Prince George had a big smile on his face.
