The birth of her son comes just a month after Lilly finally announced her pregnancy.
Lilly has done a fabulous job of flying under the media radar since the show’s series finale last spring.
Though no details have been released about the baby’s name, birthdate, birthplace, or weight, UsMagazine.com reports that Lilly and her boyfriend Norman Kali had their baby just recently.
This is the first child for both Lilly, 31, and Kali, who worked on Lost as a production assistant.
Congratulations to the new mom and dad on the birth of their baby boy!
