Britain's Princess Beatrice and her husband Edoardo Mapelli Mozzi have named their newborn daughter Sienna Elizabeth.
In a tweet on Friday, Beatrice revealed the name — in full, Sienna Elizabeth Mapelli Mozzi — alongside a picture of the newborn's footprints.
Sienna Elizabeth is Queen Elizabeth II's 12th great-grandchild. She was born on September 18 at London's Chelsea and Westminster Hospital, weighing 6 pounds and 2 ounces (2.78kg).
Beatrice, 33, is already stepmother to Mapelli's son Christopher Wolf, who is known as Wolfie, from a previous relationship.
