Cristiano Ronaldo has become a father,his website said on Sunday,although the mothers identity is being kept a secret. The Real Madrid winger and Portugal captain said: It is with great joy and emotion that I inform I have recently become father to a baby boy. As agreed with the babys mother,who prefers to have her identity kept confidential,my son will be under my exclusive guardianship. No date for the birth was given. The 25-year-old Ronaldo is not married,however since his signing by Madrid was announced he has often been photographed in the company of women. I request everyone to fully respect my right to privacy (and that of the child) at least on issues as personal as these are, he said. Calls and e-mails to Gestifute,the offices of Ronaldos agent Jorge Mendes,in Lisbon and Porto were not immediately answered. Portugal was knocked out of the World Cup by Spain and Ronaldo had a disappointing tournament. The announcement also appeared on Ronaldos Facebook and Twitter sites. Portuguese newspaper Correio da Manha reported on its Website on Sunday that Ronaldos mother,Dolores,and his sisters Elma and Katia,were dealing with the paperwork necessary to bring the child to Portugal. The paper reported that the babys mother is an American national and gave birth to Ronaldos son in early June. During 2009 Ronaldo spent time in homes the player had in Los Angeles and Miami,the paper said. Gestifute confirms the veracity of Ronaldos statement, Correio da Manha said.
