Their bundle of joy, named Paloma Louise, weighed 7 pounds, 10 ounces. Ortiz's spokesman, Tim Yates, says the family has left the hospital and is back home in Brooklyn.
Yates says Ortiz is "very excited," and has received gifts from her "Ugly Betty" co-stars.
The 38-year-old actress portrays Betty's sister, Hilda, on the popular ABC comedy. She's due to begin filming the fourth season next month.
