Berry 47, delivered her second child with French actor Martinez.
The baby boy, born in Cedars Sinai Medical Center will join his 5-year-old sister, Nahla, the child from her ex-boyfriend Gabriel Aubrey.
A source at the hospital told PEOPLE on Saturday night, “Olivier hasn’t left Halle’s side. Nahla visited her baby brother earlier today.”
Congrats to the lucky couple!
