Halle Berry and Olivier Martinez welcomed a baby boy Saturday, her rep confirms to PEOPLE.
It is a second child for the Oscar winner, who married French actor Martinez in July.
The healthy baby, who was born in Cedars Sinai Medical Center in Los Angeles, has a 5-year-old sister, Nahla, Berry’s daughter with ex-boyfriend Gabriel Aubry.
A source at the hospital told PEOPLE on Saturday night, “Olivier hasn’t left Halle’s side. Nahla visited her baby brother earlier today.”
