Sienna Miller and fiancé Tom Sturridge became proud parents of a baby girl over the weekend and her name has now been confirmed!
After giving birth in London Sienna Miller has been yet to spill the name of her newborn, but sister Savannah has taken to Twitter to share it.
Last night she shared her excitement about her new niece saying: "Marlowe I love you".
Congratulations to Sienna, Tom and Auntie Savannah, too.
