Song Joong-ki welcomed the birth of his first child, a boy, in Rome, Italy, Wednesday (14/6) local time.
"I finally met our baby in Rome, my wife's hometown. He is a healthy child," Song wrote on his fan site, quoted from Yonhap on Thursday.
"She is the most precious gift for us, with the biggest dream to make a happy family," Song added.
Song married British actress and model Katy Louise Saunders in January.
Song Joong Ki's last appearance with Katy Louise Saunders was when the two of them walked together on the sidelines of their husband's busy schedule at Cannes last month.
This is Song's second marriage after he divorced Korean actress Song Hye-kyo in 2019, his co-star in the megahit drama "Descendants of the Sun"
