Halle Berry and husband Olivier Martinez have welcomed their first child together, son Maceo Robert Martinez.

The baby was born on Saturday at Cedars Sinai Medical Center in Los Angeles, a rep for the actress confirmed to People magazine.

The baby boy, whose name means "Gift of God", is Berry's second child. She shares daughter Nahla, 5, with Canadian model Gabriel Aubry.

"Olivier hasn't left Halle's side. Nahla visited her baby brother earlier today," a hospital source told the magazine.
