She carefully drove her Range Rover past the ten-deep crowd waiting at the gates and they cheered when they saw the car going onto the palace forecourt.
The Duchess parked her vehicle discreetly around the side of the palace in order to get George from the car and left around an hour and a half later.
Meanwhile, a lot of fans of the royal family have camped in several hotels near and outside the private Lindo Wing at St Mary’s Hospital, Paddington where the Duchess is due to give birth. They are eagerly awaiting the birth of the couple's 2nd child who is going to be 4th to the throne regardless of its sex.
At about 9 am yesterday morning, Kate and her Husband Prince Williams surprised the fans by sending members of staff from the royal household to personally deliver ten cups of coffee and two boxes containing four croissants, two Danish pastries, an apple turnover and fruit bun. The two boxes of pastries and croissants were wrapped in pink ribbon, leading those desperately awaiting the royal baby’s birth to speculate it could be a girl.
A Kensington Palace spokesman confirmed that the breakfast surprise had indeed come from the couple themselves.
‘The Duke and Duchess have seen the news reports about these people camping out and they just wanted to let them know they were thinking of them,’ they said.
