Princess Charlotte's fourth birthday has been marked by the release of three pictures taken by her doting mother - and the young royal is growing up fast.
In a floral blue dress and a grin from ear-to-ear, Charlotte, who is fourth in line to the throne, looks as pretty as a petal as she sits crossed legged on a patch of grass at the palace.
The shots were taken by her mum, keen amateur snapper Kate, 37 - who has lifetime honorary membership of the Royal Photographic Society - at both Kensington Palace and the family's Norfolk home of Anmer Hall, earlier this month.
In the adorable pictures, Charlotte can be seen running and smiling as she holds a flower and sits on a fence while beaming at the camera.
