sienna miller gives birth Sienna Miller and Tom Sturridge welcome babyActress Sienna Miller and her fiance, Tom Sturridge, are new parents.

A source tells Us Weekly that Miller, 30, gave birth over the weekend. In keeping with her desire for privacy — she didn’t even talk about the pregnancy publicly until April — the baby’s gender, name and weight weren’t made available.

Miller and Sturridge, an actor whose credits include “Pirate Radio” and the upcoming “On the Road,” have been dating for a little over a year and got engaged in early 2012.

Miller has several independent movie projects due for release in the next year and also plays Tippi Hedren in “The Girl,” a BBC/HBO movie about the actress’ relationship with director Alfred Hitchcock.

As details on the baby come to light, we’ll keep you updated.
