THERE is nothing in the world like a kiss from a loving sister.

Tenderly cradling her new baby brother’s head, Princess Charlotte showed just how she felt about little Prince Louis, welcoming him to the Royal Family with a cuddle.

The relaxed family shots are the first official pics of the tiny prince.

Taken by the Duchess of Cambridge on Charlotte’s third birthday, on May 2, the touching images, were shot at their apartments at Kensington Palace.

It gives a rare insight into the private world of the most talked about family in the world.

And it is not the first time the Duchess has released Royal photographs.

A keen amateur snapper, Kate, 36 – who gave birth to Louis on April 23 – last year accepted a lifetime honorary membership of the Royal Photographic Society which recognised her talent.
