Halle Berry is officially on diaper duty again. E! News has learned that the Oscar winner delivered a baby boy Saturday at Cedars Sinai Hospital in Los Angeles, her first child with hubby Olivier Martinez.

This is the second child for the Oscar winner, who is also mom to 5-year-old Nahla, her daughter with ex-Gabriel Aubry. Martinez first revealed that he and his stunning wife were expecting a boy in June, with The Call star telling People, “My son will remain an American, but I will remain French.”
