Happy Birthday Princess Charlotte!!
Princess Charlotte, whose full title is Her Royal Highness Princess Charlotte Elizabeth Diana of Cambridge, was born at the Lindo Wing at St Mary's Hospital in Paddington at 8.34am on May 2 2015, weighing 8lb 3oz.
She is the second child of the Duke and Duchess of Cambridge, and a sister to Prince George, five, and Prince Louis, one.
Her adorable grin, impish confidence and playful nature mean that at the age of four Princess Charlotte is already a favourite with royal fans.
And as these official photographs show, many of her loveable traits have clearly been passed down the line.
For Charlotte is an action girl, just like her mother the Duchess of Cambridge.
The three new images, taken by keen photographer Kate, have been released to mark the princess's fourth birthday today.
They were taken last month at the family's homes at Kensington Palace and Anmer Hall.
Throughout her life, Kate has been documenting her daughter's milestones by taking her own portraits, rather than calling in a professional.
Kate is a keen and accomplished amateur photographer who has lifetime honorary membership of the Royal Photographic Society which recognised her 'talent and enthusiasm'. Read more from The Daily Mail.
