The Duchess of Sussex gave birth to her second child, a daughter to be called Lilibet 'Lili' Diana Mountbatten-Windsor, on Friday in California, according to a statement from Harry and Meghan's press secretary and foundation.
Lili was said to be named after her great-grandmother, Queen Elizabeth II, whose family nickname is Lilibet, while her middle name is that of Harry's mother, Diana, the late Princess of Wales, the statement on Sunday said.
"She is more than we could have ever imagined, and we remain grateful for the love and prayers we’ve felt from across the globe," Harry and Meghan said.
Both mother and child are healthy and well after the delivery in Santa Barbara Cottage Hospital in California.
Harry and Meghan had previously revealed in a high-profile interview with TV host Oprah Winfrey in March that they were expecting a girl.
The couple, who live in California together, already have a 2-year-old son named Archie Harrison Mountbatten-Windsor.
