The Duke and Duchess of Cambridge, who have been widely rumoured to have a frosty relationship with Harry and Meghan since the pair quit official royal duties to move to America last year, posted their well-wishes on their official Instagram page.
"We are all delighted by the happy news of the arrival of baby Lili," they wrote.
"Congratulations to Harry, Meghan and Archie."
The pair accompanied their statement with a black and white picture of Harry and Meghan cradling baby Archie.
Baby Lilibet was born on Friday 4th June, at 11.40am, with the Duke and Duchess of Sussex announcing the news on their Archewell website.
The statement reads: "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 11:40 a.m. in the trusted care of the doctors and staff at Santa Barbara Cottage Hospital in Santa Barbara, CA.
"She weighed 7 lbs 11 oz. 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."
Harry and Meghan added: "On June 4th, we were blessed with the arrival of our daughter, Lili. 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. Thank you for your continued kindness and support during this very special time for our family."
