Sienna Miller has been shy about acknowledging her pregnancy. And she isn't being vocal about her baby news.
But Us Weekly reports that the actress, 30, and her fiance, Tom Sturridge, welcomed a baby daughter to the family over the weekend in London.
Today, E! News says the couple have named the baby Marlow.
iVillage.com says the name "screams pure awesome girl power."
Entertainmentwise.com suggests the couple was inspired "by Charles Marlow, British writer Joseph Conrad's alter-ego who narrated several of his most famous novels including Heart Of Darkness. Or perhaps it was after the Buckinghamshire town of Marlow?"
Glamour's U.K. site says that the child "is rumoured to be named after the famous Elizabethan playwright Christopher Marlowe."
