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."
"I remain a Frenchman in America, but I adapt to American culture," Martinez continued. "I feel good there—but I'm still a foreigner. My son will be an American."
In April, the couple's rep confirmed rumors that Berry was concealing a baby bump, telling E! News, "We can confirm that Halle Berry and Olivier Martinez are expecting a child. We will not be commenting on or confirming any additional details."
Before the couple made their big baby news announcement, Berry made an appearance on the Wendy Williams Show last November dishing on Nahla's desire to be a big sister.
"Every night, we do our prayers," Berry said during a November appearance on The Wendy Williams Show. "We pray to God, so sweet. She says, 'God, please bring me a bunk bed and a baby sister.' And I say, ‘I can do one of those things, I know for sure. The other one, we've got to keep praying on.'"
The adorable tyke soon got her wish.
Berry's second pregnancy did little to slow her down.
Once the mother-of-two gets settled, she's set to star in Steven Spielberg's new CBS drama Extant, in which she'll play an astronaut who returns home after a year-long solo mission in space.
The series is scheduled to air in summer 2014.
