Los Angeles - Sienna Miller has had a baby girl.

The 30-year-old actress and her fiancé Tom Sturridge, 26, welcomed their first child into the world over the weekend in London and the gender of the tot has now been revealed.

A source has confirmed the baby's sex to UsMagazine.com and according the Daily Mail her name is Marlow.

Although news of Sienna's pregnancy broke earlier this year, the GI Joe: Rise of Cobra star was very reluctant to talk about it.

Strict instructions not to say anything

The blonde beauty admitted she did not want to share details of the pregnancy because she didn't want anything to jeopardise her attempts to keep her private life out of the public domain.

In March, she said: "I'm in my second trimester, so I'm I-can-talk-about-it pregnant, 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."

Sienna started dating The Boat That Rocked  actor Tom - who is friends with Robert Pattinson - just a few months after she split from fiancé Jude Law for a second time in February 2011.
