The newborn British princess on Saturday evening made her first public appearance, along with her parents, the Duke and the Duchess of Cambridge, outside St. Mary's Hospital where she was born.
The baby girl, born at 8.34 a.m., was presented by her parents to the world at 6.10 p.m., Xinhua reported. She weighs about 3.7 kg.
Her parents -- Duchess Catherine and Prince William -- looked relaxed, with smiles on their faces.
The Duchess was holding her baby in her arms, while the princess was asleep.
The couple did not say anything to the media.
When he went to Kensington Palace on Saturday afternoon to take his son to the hospital, William said he was "very happy" at the arrival of his second child.
The princess' older brother, Prince George, met his sister in the afternoon.
The royal family then left the hospital for Kensington Palace, which is just a few minutes away.
Kensington Palace, in a statement on Saturday morning, said: "Her Royal Highness and her child are both doing well."
The newborn princess is now the fourth in line to the British throne, after Prince George, father Prince William and grandfather Prince Charles.
Prime Minister Harper, Gov. Gen. Johnston welcome birth of Princess of Cambridge
TORONTO — Prime Minister Stephen Harper and Gov. Gen. David Johnston are welcoming the birth of a princess in London.
Royal officials say the Duke and Duchess of Cambridge's daughter "was safely delivered" Saturday morning, less than three hours after checking into St. Mary's Hospital.
The newborn's name wasn't immediately announced but when her brother, Prince George, was born in 2013 royal officials waited two days before announcing his name.
Harper, who is on a surprise visit to Iraq, issued a statement saying "all Canadians were delighted today to learn of the birth of Her Royal Highness The Princess of Cambridge."
Harper says the Royal Family "holds a very special place in our country" and offered "heartfelt congratulations and very best wishes to the happy family."
Johnston said in a release that the new princess "will find an outpouring of affection from all Canadians and from people across the Commonwealth." Canadians can write wishes to The Duke and Duchess of Cambridge on the Governor General's website.
