According to British tabloid The Sun, the athlete will “very soon” become a father to twins via surrogacy.
The surrogate mother is reportedly an American woman from the US West Coast.
The tabloid claims that the babies will be flown to the Portuguese sport star’s multi-million-euro mansion in the upmarket La Finca neighbourhood in Madrid, once they are born.
Ronaldo is already father to Cristianinho, six, whose conception is also shrouded in mystery.
Confronted by journalists during the inauguration of a gym belonging to a chain he represents as to whether the rumours hold any truth, the athlete apparently dodged the question, opting to neither confirm nor deny the reports.
