Halle Berry is celebrating being a mother again.

The Oscar winning actress gave birth to a baby boy in Los Angeles on Saturday, who is the first child for Halle and husband Olivier Martinez.

This is the second child for the 47-year-old Die Another Day star, who has a five-year-old daughter, Nahla, with ex-fiancé Gabriel Aubry.

E! Online reported that Berry had delivered her latest bundle of joy at Cedars Sinai Hospital, where countless celebrity children have been born over the years.

The delivery came just a day after the Catwoman star had been spotted out in West Hollywood at restaurant Rivabella looking ready to pop in a sheer shirt covering her huge bump.

Berry had recently revealed that she was thrilled to be pregnant again, having previously called the conception a 'miracle' due to her older age.

As for the first-time dad, the Parisian S.W.A.T. actor told People: 'My son will remain an American, but I will remain French,' he explained. 'I remain a Frenchman in America, but I adapt to American culture.'

Berry and Martinez were married in a stunning ceremony in Vallery, France, in July where she wore a beautiful Jenny Packham gown.

The Monster's Ball Oscar winner was previously married to baseball player David Justice in the early 1990s and to singer Eric Benét in the early 2000s.

While motherhood is obviously the only thing on her mind right now, the 47-year-old actress has just signed on to star in a serialised drama coming to CBS next summer called Extant, a 13-episode thriller.

Berry will play an astronaut trying to reconnect with her family when she returns after a year in outer space. Her experiences lead to events that change the course of history.

The series is being made in partnership with Steven Spielberg's Amblin Television, which made last summer's surprise hit for CBS, Under the Dome.
