Alba, 30, announced on Facebook that her second daughter came into the world yesterday.
“She was born on Saturday, weighed 7 lbs. and was 19 inches long,” she wrote. “Healthy and happy! Big sister Honor couldn’t be more excited about the new addition to our family.”
“Thank you for all of your support during my pregnancy,” the post continued. “It means the world to me.”
Jessica Alba and husband Cash Warren are already parents of 3-year-old daughter Honor.
For this second birth, the actress said she felt more relaxed. This time, Jessica has taken HypnoBirthing classes. The technique allows an expectant mother to give birth while being relaxed.
Jessica announced her second pregnancy via Facebook and Twitter in February.
