The 30-year-old spoke of his desire to have 'five or six' little Cristianos in a recent magazine interview.
He told FHM magazine: 'I think I have good conditions to have many kids so I want this. Let's find the right woman.'
Cristiano Ronaldo vowed that the identity of his son's mother will never be known.
Ronaldo's mum revealed in her approved biography she had picked up Cristiano Jr, known affectionately as Cristianinho - 'little Cristiano', from a private hospital in Florida.
Cristiano was pictured getting VIP treatment at a basketball match and relaxing bare-chested round his hotel pool while his son stayed with his grandmother more than 3,800 miles away.
Dolores, who this year opened her own Twitter and Instagram pages, posted a string of pictures of her surrounded by her grandchildren including Cristianinho over Christmas in her native Madeira.
