William and Kate could not contain their happiness as they left hospital holding their daughter, who is fourth in line to the throne.
The baby, whose name had not yet been announced last night, was born at 8:34am weighing 8lbs 3oz, less than three hours after the couple arrived at the Lindo Wing at St Mary’s Hospital in London.
Kate cradled her daughter in her right arm and the baby, wrapped in a shawl and wearing a bonnet, appeared fast asleep. The Duchess smiled broadly, as did the Duke, who had his arm around his wife as they both waved to the media and the crowds.
Kate looked relaxed and in good health despite giving birth some 10 hours before, and wore a yellow and white floral print dress.
After spending a few minutes posing for pictures they walked back inside the Lindo Wing and soon returned with their daughter in a baby seat.
Earlier, proud father William beamed with joy and said he was “very happy” following the birth of his new baby.
He smiled and waved to the crowd of well-wishers as he left the hospital to collect Prince George to bring him to meet his new little sister.
“We’re very happy, thank you. I’m just going to pick up George,” said the proud father as cheers erupted in the crowds.
Later Prince George waved to the crowds as he was brought to hospital to meet his new baby sister. There were excited shouts from the public and the Duke smiled as he posed for a picture with his son. The blonde-haired toddler, who is 21-months-old, seemed at ease with the enthusiastic crowd.
The announcement of the birth left the Prince of Wales - who said he wanted his second grandchild to be a girl - and Duchess of Cornwall “absolutely delighted”, Clarence House said.
The Queen wore pink for a girl and beamed with happiness yesterday afternoon when well-wishers applauded and congratulated her on the birth of her fifth great-grandchild.
William’s uncle Earl Spencer also reacted with joy to the announcement, saying: “It’s wonderful news - we are all thrilled for all four of them.”
Other members of both families - the Windsors and the Middletons - were informed including Prince Harry who is on the other side of the world in Australia.
In a modern twist, the birth of the princess was announced formally to the world via Twitter and also when a bulletin, printed with the details of the delivery, was placed on an easel erected in the forecourt of Buckingham Palace.
The ornate gold easel was the same one used to proclaim to the nation George’s birth in 2013.
The brief bulletin - on foolscap-sized paper set in a dark wooden frame - was put into place by two footman and it said the Duchess was “delivered” of a daughter and gave the time of birth.
It was signed by a senior medical team led by consultant obstetrician Guy Thorpe-Beeston, surgeon-gynaecologist to the household, who delivered the royal baby.
Alan Farthing, the Queen’s surgeon gynaecologist, who was engaged to popular BBC presenter Jill Dando when she was shot and killed in April 1999, was also part of the team.
The baby’s name was not known last night but Alice and Charlotte were the most popular among bookmakers.
