Princess Charlotte has started her first day at school, following in the footsteps of big brother Prince George.
Charlotte, who celebrated her fourth birthday on 2 May, started at Thomas's Battersea in south London on Thursday morning.
The Duke and Duchess of Cambridge took her on the first school run together, while George, six, will show her the ropes as she starts her school career.
Known for often giving a wave or cheekily stickingout her tongue in public, Charlotte appeared to be a bit shy as the family arrived at the school, momentarily hiding behind her mother as she held her hand.
She was wearing her new school uniform, a navy blue dress and a navy cardigan with red piping, as she walked excitedly on her tip toes and played with her ponytail.
The Duke said his daughter was "very excited" for her first day.
She quickly got over her shyness as Helen Haslem, head of Thomas' lower school greeted her with a hand shake.

Having spent two years at the school, George appeared at ease, in contrast to his first day in 2017 when he clung to his father's hand and shook Ms Haslem's hand with a degree of bewilderment.
Kate was unable to accompany George on his first day as she was less than 12 weeks pregnant with her third child, Louis, and suffering from hyperemesis gravidarum – a condition that can mean vomiting up to 50 times a day.
The Duchess looked excited to be able to take her second child to school, laughing as the family walked in.
