Who is Cristiano Ronaldo's son Cristiano Ronaldo Jr?

CRISTIANO RONALDO is now a proud father of five.

However, the birth of his new baby daughter was marked by tragedy as Ronaldo and Georgina Rodriguez revealed the sad death of her twin brother.

The oldest of Ronaldo's children is Cristiano Ronaldo Jr, who is now a promising footballer himself.

Who is Cristiano Ronaldo Jr?

Cristiano Ronaldo Jr was born in San Diego in 2010.

In the family, he is nicknamed 'Cristianinho', which means 'Little Cristiano'.

And he is already living up to that billing, having joined the Man Utd academy.

Cristiano Jr has also been regularly seen performing his father's famous "siiiu" celebration when scoring for the Red Devils U12s.

Proud dad Ronaldo often shares pics and videos of his son's incredible football skills.

The identity of Cristiano Ronaldo Jr's mother is not known and Ronaldo Sr says he will never reveal it to the public.

However, he did say that he would inform Cristiano Jr when he feels he is old enough to know the truth.

He told Jonathan Ross: "People speculate I was with this girl or another, or there was a surrogate mother.

"I have never told anyone and never will.

"When Cristiano [Junior] is going to grow up, I am always going to say the truth to him because he deserves it, because he is my son.

"But I am not going to say [it just] because people want me to say."

Ronaldo added that he did not believe it would be an issue for Cristiano Jr to grow up without his mother.

He commented: "For me it's not a problem.

"In the world, many kids do not have a mum or have dads, or dads die and mums die, or they beat them up."

Ronaldo then joked: "Cristiano has a dad – unbelievable dad!

"He has a grandfather, grandmother, [he] has the support of my family."
