Halle Berry and Olivier Martinez are the parents of a brand new baby boy.

The newlyweds welcomed a son at Cedars Sinai Medical Center in Los Angeles on Saturday night, a rep told PEOPLE. A source tells PEOPLE that “Olivier hasn’t left Halle’s side. Nahla visited her baby brother earlier today.”

This is the second child for Berry, 47, who has a 5-year-old daughter with her ex-boyfriend, Gabriel Aubry. This is the first child for Martinez. The couple married in July.

Earlier this year, Berry called her pregnancy “the biggest surprise” of her life. “I thought I was kind of past the point where this could be a reality for me,” she told CNN. “So it’s been a big surprise and the most wonderful.”

Congrats to Halle and Olivier!
