Prince William and Kate Middleton have released pictures of Princess Charlotte, just in time for her first birthday!

The pictures were tweeted by Kensington Palace and were taken by the Duchess of Cambridge at the Royal Couple's Norfolk home.

A Kensington Palace spokesman said ''The Duke and Duchess are delighted to share new photographs of Princess Charlotte''

The young royal was introduced to the public on the day of her birth, May 2 2015, and like her older brother Prince George, those first images of the tiny infant were captured by the waiting media.

She was named Charlotte Elizabeth Diana in tribute to her Grandmother Diana and her Great-Grandmother the Queen.

Charlotte's privacy has been carefully guarded by the family over the past year and she has only been seen on one other occasion, her christening.
