London, July 21 :Cristiano Ronaldo‘s sister Elma Aveiro has recently revealed that even after four years his son still has no clue about who his mother is. Aveiro said that Cristiano Jnr, dubbed Cristianinho, has stopped asking about the woman, who was believed to be a surrogate, however, the 29-year-old footballer told her that the mum would never be known, the Mirror reported.

Once they told him she was in Heaven, but Ronaldo and her mother asked them not to repeat it, so now they just tell him that she was travelling, she added. Questions about the woman surfaced again last week when Ronaldo’s mum Dolores Aveiro released an official biography in which she revealed she went to the US to pick up Cristianinho after his 2010 birth.
