My, how you've grown! Britain's Princess Charlotte turns 1

Princess Charlotte celebrates her first birthday on May 2. There's no word on how the family plan to mark the occasion, but Kensington Palace has released four new pictures of the youngest member of the royal family.

In one of the pictures Charlotte, wearing a little pink cardigan with a matching pink bow in her hair, can be seen pushing her walker across a lawn.

In another she gazes thoughtfully at the camera and appears relaxed and happy - perhaps because her mother, the Duchess of Cambridge, was the one behind the lens.

A third photograph shows her leaning on a wooden chair, this time wearing a cream cardigan over a blue dress with a blue ribbon clip in her hair and the final photograph shows Charlotte's startling resemblance to George as she clambers on a wicker chair, playfully glancing back towards the camera.

The royals released the images on Sunday morning on their Twitter account and said: “The Duke and Duchess are delighted to share new photographs of Princess Charlotte. The Duchess took these pictures of her daughter in April at their home in Norfolk. The Duke and Duchess are happy to be able to share these family moments, ahead of their daughter's first birthday. We hope that everyone enjoys these lovely photos as much as we do.”

The young royal was first introduced to the public on the day she was born, May 2 2015, and like her older brother the images of the tiny infant were captured by the world’s media.
