The actress’s rep says: “Jennifer Garner and Ben Affleck gave birth to a healthy baby girl.”
The baby was born Tuesday in Los Angeles. No other details were immediately available.
Garner and Affleck, both 36, are also parents to daughter Violet, 3.
In the weeks leading up to the birth, Garner, stayed close to home, picking up Violet from preschool and even treating herself to a mani-pedi.
Just days before giving birth, Garner was spotted with Violet at the Farmer’s Market in Pacific Palisades and grabbing a decaf coffee at Caffe Luxxe in Santa Monica with a girlfriend.
Former Alias costar and close friend Victor Garber says the actress needs no help in the mommy department.
“It’s her second child,” Garber told PEOPLE. “She knows what to do. She’s probably the best mother I’ve ever witnessed.”
Garner confirmed her second pregnancy in August.
