The 36-year-old actress, who is mom to 18-month-old Autumn James, gave birth on Wednesday to a son.
The couple named their little boy Atticus James, according to ABC News.
Hewitt, who recently became the face (and then belly) of Palmer's cocoa butter, had kept the gender of her unborn baby and his due date a secret.
While she hasn't yet said what inspired her new baby's name, we are noticing a fun "first initial A, middle name James" trend. Looks like her two little ones will share more than their parents and a last name.
We'd also venture to guess that she's a fan of Harper Lee's novel "To Kill a Mockingbird" and its famed character Atticus Finch. Now that's a role model!
