Confirming the birth of her first child with girlfriend, Ronaldo took to his Instagram account and posted a picture of a happy couple with the star striker's eldest son and new-born baby girl called Alana Martina.
He captioned the picture, "Alana Martina is just born! Both Geo and Alana are doing great! We are all very happy!"
Alana, who cannot be seen in the picture, arrived nine days earlier than anticipated at a Hospital Quiron Universal near Ronaldo's home.
Prior to the birth, Georgina and Ronaldo had decided to reveal the baby's name, the Mirror reported.
The Portuguese star had said that he selected the first name while Georgina decided the second.
"The name of my daughter will be Alana Martina. I just wanted to share this with you. I think it is a beautiful name," Ronaldo had earlier said.
In June, Ronaldo welcomed birth of his twins, Eva Maria and Mateo, from a surrogate mother in the United States.
Ronaldo also has a son, Cristiano Jr., who was born in 2010. (ANI)
