Sienna Miller has been keeping mum on the sex and name of her baby after she gave birth over the weekend.
But it has now been reported she and fiance Tom Sturridge welcomed a baby girl and have named her Marlowe Ottoline Layng.
However, the couple are still to confirm this officially and have not yet revealed any details about their child's birth.
The actress, famous for her roles in Alfie, Layer Cake, G.I Joe and Factory Girl, is notoriously private, but touch on the subject briefly in an interview with Vogue UK in April.
She told the fashion magazine: "Even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years.
"I'm feeling fine. It's all progressing nicely and it's very exciting," she added.
