Cristiano Ronaldo’s mum has sensationally confessed she tried to abort the football star before he was born.

Dolores Aveiro said she opted for a home recipe involving warm beer and mad exercise after a doctor refused to help her interrupt her pregnancy.

She made the stunning admission in a warts-and-all biography out yesterday in Portugal.

In the book, titled ‘Mother Courage’, she revealed: “I wanted to abort but the doctor didn’t support my decision.”

She went on to explain she drank warm ale and “ran till she dropped” without achieving her aim.

Speaking at the launch of the book, which Cristiano missed because of work commitments, she said the Real Madrid star knew of her secret and was able to joke about it.

She confessed: “He told me when he found out, ‘Look mum, you wanted to abort and now I’m the one who’s pulling the purse-strings in the house.”

Dolores, whose late husband Dinis died from liver damage caused by alcoholism, also spoke about Cristiano’s son Cristiano Jr, three.

The footballer has managed to keep the youngster’s mum identity a secret, with reports over the years claiming she is everything from a surrogate mum to a woman he had a one-night stand with.

The pair were pictured together earlier this year at the Madrid Open Tennis tournament.

Dolores revealed in the approved biography, written by a Portuguese author, that she picked the child up from a clinic in Florida while Cristiano was playing in the 2010 World Cup in South Africa.

Speaking of the moment Cristiano told her he would be a father, she added: “I’m going to have a child and I want you to be the one to help me educate him and give him love, as you’ve always done with me and my brothers and sisters.”
