The baby, who was born overnight, has been named Lilibet “Lili” Diana Mountbatten-Windsor. The name makes reference to both her grandmother, Princess Diana, and her great grandmother, the Queen (Lilibet was the Queen’s family nickname and the name Prince Philip used to call her).
“Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet,” the couple explained.
“Her middle name, Diana, was chosen to honour her beloved late grandmother, The Princess of Wales.
The baby was born just before midday and weighs 3.5kg.
“It is with great joy that Prince Harry and Meghan, The Duke and Duchess of Sussex, welcome their daughter, Lilibet “Lili” Diana Mountbatten-Windsor, to the world," the couple said in a statement.
“Lili was born on Friday, June 4 at 11.40am in the trusted care of the doctors and staff at Santa Barbara Cottage Hospital in Santa Barbara, California.
“She weighed 7lbs 11oz (3.5kg). Both mother and child are healthy and well, and settling in at home.”
Some of the biggest names in Hollywood are being tipped as possible godparents to Meghan Markle and Prince Harry’s newborn daughter after the couple welcomed Lilibet Diana.
According to The Sun, Oprah Winfrey is not the only strong woman who could make the cut as godmother to Lilibet, with TV host Gayle King and tennis superstar Serena Williams also being tipped as contenders.
TV host King has become a mouthpiece for the couple – revealing in April it was “no secret” Harry and William’s relationship was “strained”.
The couple have also asked anyone wishing to send a present to instead “support or learn more” about organisations working for women and girls.”
According to a statement, the Queen and her family are “delighted” at the birth of a daughter to her grandson.
“The Queen, The Prince of Wales and The Duchess of Cornwall, and The Duke and Duchess of Cambridge have been informed and are delighted with the news of the birth of a daughter for The Duke and Duchess of Sussex,” a palace spokeswoman said.
British Prime Minister Boris Johnson also sent his congratulations.
“Many congratulations to The Duke & Duchess of Sussex on the birth of their daughter,” Johnson wrote on Twitter.
As for Meghan’s father Thomas Markle, even he told Sun Online that he's “very pleased that my daughter and my new granddaughter had a successful delivery.
“I wish them all my love and the best of luck.”
