Cristiano Ronaldo will tell son who his mum is, but says the world will never know

Cristiano Ronaldo says he will tell his son about his biological mother when the time is right, but the outside world will never know.

The Real Madrid star has kept the identity of the five-year-old’s mother private but said he is “100%” sure his son, also called Cristiano, will understand.

Ronaldo, seen as a heartthrob by many, also said he has “a few” love interests at the moment.

The 30-year-old told ITV chat show host Jonathan Ross he does not think it is a problem that his son does not have a relationship with his biological mother.

“For me it is not a problem,” he said.

“I will say in the world, many kids don’t have mum, don’t have dads, or dads die or mums die... Cristiano has a dad, an unbelievable dad.”

The Portuguese star said his son also has the support of his grandmother, Ronaldo’s mother, adding: “Listen, some points in life it’s private and people have to respect the privacy of other people.

“When Cristiano is going to grow up, I am always, always going to say the truth to him because he deserves, because he is my son but I am not going to say because people want me to say.”

When asked at what age he will share that information, Ronaldo said: “I’m not worried about that, he’s going to understand his daddy, he is going understand I am sure 100%. 100% he is going to understand me.

“I’m going to say the time when I feel that the time, that is the right time. I don’t know... 10, 11, 12? “I don’t know, let’s see.”

Ronaldo, who is the subject of an eponymous documentary which is now on general release, told the show he would like more children. “Yes, a few more, I want three, four more,” he said.

Ross asked if there was a “special someone” in Ronaldo’s life, and he replied: “A few.”

His mother speaks about him being an unwanted child in the documentary, and when asked how he felt about this, Ronaldo told the show: “Normal... Not just me, it doesn’t change anything in my mind. As I said before, I was a special kid and I help all my family so I am happy, very happy.”

On the contrast of his son’s life to how his life was growing up, Ronaldo spoke about how much he values education. “It’s all about education, you have to give good education and pass to him.”

The Jonathan Ross Show airs at 9.45pm tomorrow.
