Oh brother, such royal cuteness

PROUD big sister Princess Charlotte plants a loving kiss on the face of her brother Prince Louis (above) in their first royal photocall together.

In a second snapshot, pink-cheeked Louis looks alert (right) as he takes in his surroundings at Kensington Palace just three days after his birth.

The touching snaps, taken by the children’s mother Kate, 36, were released at the weekend. They are the first glimpses of the prince since he left St Mary’s Hospital, west London, where he was born on April 23.

London newspapers reported the junior royals both wore hand-medowns in the photos.

Charlotte’s cardigan was donned by older brother Prince George in a portrait to mark the Queen’s 90th birthday, while Louis’ knitted outfit was worn by Charlotte in her first official photos.

The new images show Charlotte, who turned three last Wednesday, warming to her big-sister role, resting Louis in her lap and placing a protective arm around him on her birthday.

Outgoing Charlotte won hearts when she waved to crowds outside the hospital when she arrived to meet Louis for the first time with her father William and George, 4.

The palace said William and Kate wanted to thank the public for the kind messages they had received after the birth of Louis, and for Charlotte’s third birthday.
