There was lots of excitement outside the hospital when the birth was announced. There was even a town crier.

The little princess's big brother George also came to visit and waved to the crowds with his father.

Lots of photographers and journalists were waiting outside, as well royal fans, some of whom have been camped outside the hospital for weeks.

The new arrival was born in the Lindo Wing at St Mary's Hospital where the duke and duchess's first child, Prince George, was born in July 2013.
