Princess Beatrice and husband Edoardo Mapelli Mozzi have named their newborn daughter.
Sienna Elizabeth Mapelli Mozzi was born at 11.42pm on September 18 at London’s Chelsea and Westminster Hospital, weighing 6lb 2oz.
The Queen’s 12th great-grandchild is 11th in line to the throne and is Beatrice’s first child.
Edoardo, an Italian count and millionaire property tycoon, is already a dad to his five-year-old boy Christopher Woolf, nicknamed Wolfie, who the Princess calls her ‘bonus son’.
Princess Beatrice and husband Edoardo daughter’s name was announced by the Royal Family on Friday on their official social media handles with an adorable photo of Sienna’s footprints.
In a message, the couple said: ‘We are all doing well and Wolfie is the best big brother to Sienna.’
On Instagram, Edoardo, 38, who also goes by Edo, said: ‘Sienna Elizabeth Mapelli Mozzi. Our life together has just begun, and I can’t wait to see all the amazing things that await us.
‘Feeling so much love and gratitude for my amazing wife, baby Sienna and Wolfie. These are the days I never want to forget.
‘This week, a friend said to me the sweetest saying….that with every child you grow a whole new heart.
‘A massive thank you to the Midwife and the amazing team at the Chelsea and Westminster Hospital.’
As per palace protocol, the latest addition to the family is not entitled to an HRH title, but she will inherit a nobile donna (noble woman) title from her dad.
Princess Beatrice and husband Edo tied the knot in July 2020 in a secret lockdown wedding attended by the Queen and Philip after their planned ceremony was postponed because of the pandemic.
Sienna is the second great-grandchild of the Queen to be born since the Duke of Edinburgh’s death in April, with Prince Harry and Meghan Markle bringing Lilibet into the world in June.
Beatrice, 33, is the eldest daughter of the Duke of York and his ex-wife Sarah, Duchess of York, with the baby being the Yorks’ second grandchild.
