Pippa Middleton will meet her new nephew this evening after travelling to Kensington Palace to celebrate the arrival of the Duke and Duchess of Cambridge's first child.
The Duchess of Cambridge's sister travelled to the west London palace with her boyfriend Nico Jackson.
Prince William and Kate were pictured arriving into the grounds of Kensington Palace after earlier leaving the private Lindo Wing at St Mary's Hospital in London.
They waved in front of screaming crowds and masses of journalists from around the world as they left the hospital, 26 hours after the heir to the throne was delivered, weighing 8lbs 6oz.
The proud parents are expected to spend two weeks at Kensington Palace while William is on paternity leave.
