THE Duke and Duchess of Sussex are celebrating the arrival of their baby daughter, who they have named Lilibet "Lili" Diana Mountbatten-Windsor.

Meghan gave birth to her second child on Friday, June 4, at 11.40am at Santa Barbara Cottage Hospital in Santa Barbara.

The baby - a younger sister for the Sussexes' two-year-old son Archie Mountbatten-Windsor - weighed 7lbs 11oz.

A statement from the couple's press secretary said: "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.

"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. Both mother and child are healthy and well, and settling in at home.

"Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet.

"Her middle name, Diana, was chosen to honour her beloved late grandmother, The Princess of Wales.

"This is the second child for the couple, who also have a two-year-old son named Archie Harrison Mountbatten-Windsor.

"The Duke and Duchess thank you for your warm wishes and prayers as they enjoy this special time as a family."

The new baby is the Queen's 11th great-grandchild - poignantly the first of the monarch and Philip's great-grandchildren to be born since the death of the duke in April.

But with the Sussexes living in California and amid troubled relationships with their family, it is not known when or if the new addition will meet the Queen and the rest of the royals.

The new baby will be entitled to be a princess and Archie a prince - both with HRH styles - after the death of the Queen and when Charles becomes king.

This is because they will have moved up the line of succession to become the children of a son of a monarch.

Despite Harry and Meghan quitting as senior working royals, the baby still has a place in the line of succession.

She is eighth in line to the throne, coming after Archie, who is seventh in line, and before the Duke of York, who has dropped to ninth place.

The new baby is also a first cousin of Prince George, Princess Charlotte and Prince Louis and a fifth grandchild for Charles, but will grow up across the Atlantic, thousands of miles away from the royal family

2021 is proving to be a bumper year for royal babies.

Princess Eugenie welcomed a son August in February, while Zara Tindall had a boy Lucas in March, and Princess Beatrice is expecting her first child, who will be the Queen's 12th great grandchild, in the autumn.
