Garces, 39, and her husband Antonio Hernandez welcomed Antonio Andres Hernandez, who weighed in at 7 pounds and 5 ounces.
"After a difficult 14-hour labor, my mom had to have an emergency c-section," Garces' daughter Skye told the magazine. "My brother was born beautiful and healthy, thank God, and Mom is doing well also."
This is Garces' first child with Hernandez, whom she married in 2002. Skye is from a previous relationship.
