Duke and Duchess of Cambridge Release First Official Family Portrait with Prince Louis

The Duke and Duchess of Cambridge have released their first official family portrait with their newborn son, Prince Louis.

The beautiful portraits were taken to mark the christening of the young prince, which took place on Monday afternoon at St James's Palace in London.

The pictures were taken by Royal photographer Matt Holyoak in the morning room at Clarence House.

In one of the photographs, the young prince is pictured with his mother and father, as well as big brother Prince George and sister Princess Charlotte.

Mr Holyoak, who previously photographed the Queen and Prince Philip last year on their 70th wedding anniversary, took the four official photographs at Prince Charles' official residence.

The family portrait sees the proud parents with their children and Kate's parents, Michael and Carol Middleton.

Other guests include Pippa Middleton and her husband James Matthews, James Middleton, the Prince of Wales, the Duchess of Cornwall and newlyweds Prince Harry and Meghan Markle.

One of the four pictures, shows the doting mother share a sweet moment with little Louis as she held him in her arms in the garden at Clarence House, holding her son up close to her chest.

It's clear for the world to see how enamoured the royal is with her newborn baby.

Photographer Matt Holyoak said of being chosen for the special day, “I was truly honoured at being asked to take the official photographs at the christening of Prince Louis, and to witness at first hand such a happy event.

Everyone was so relaxed and in such good spirits, it was an absolute pleasure.

I only hope I have captured some of that joy in my photographs.”

The tiny prince looked simply adorable in a cream gown which many royal babies before him have worn.

The robe, which was created by the Queen's dresser Angela Kelly, is a replica of the intricate lace and satin dress made for Queen Victoria's eldest daughter in 1841.

The special occasion was Louis' first public appearance since he made his debut on the steps of the Lindo Wing in April, and it marked the Cambridge family's first outing as a family of five.

Louis, who is fifth in line to the throne, was christened at the Chapel Royal of St James's Palace, the same venue where Prince George was also welcomed into the Christian faith in October 2013.
