The Duchess of Sussex has given birth to her second child, a baby girl named Lilibet Diana.

Meghan Markle and Prince Harry welcomed the new arrival to the family on Friday, making their 2-year-old son Archie Harrison an older brother.

"Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet," the couple said in a statement. "Her middle name, Diana, was chosen to honor her beloved late grandmother, The Princess of Wales."

The royal baby is eighth in line to the British throne after Archie, who became seventh in line upon his birth on May 6, 2019.

She is the younger cousin of Prince William and Kate Middleton's children, Prince George, Princess Charlotte, and Prince Louise, and Queen Elizabeth's 11th great-grandchild.

It's likely the baby will be raised in Santa Barbara, California, where the family has resided since the Sussexes purchased their first home there last year.

Harry and Meghan announced the baby's gender during their interview with Oprah Winfrey in March, and said they had no plans to have more than two children.

"To have any child, any one or any two would've been amazing, but to have a boy and then a girl - what more could you ask for?" Harry said. "Now we've got our family. We've got the four of us, our two dogs."

The couple announced that they were expecting their second child on Valentine's Day.

"We can confirm that Archie is going to be a big brother. The Duke and Duchess of Sussex are overjoyed to be expecting their second child," a spokesperson said in a statement obtained by Insider.

Along with the statement, the couple shared a previously unseen black-and-white photo, which showed the duchess with her hand on her stomach.
