Katia Aveiro has been caring for the Real Madrid hunk's love child while he's been away in the States.
'He's called Cristiano Ronaldo just like his dad,' she says.
'Cristiano chose the name but we like it. He looks like his father and like me.'
The 25-year-old announced on his Facebook account over the weekend that he had fathered a son with an unnamed woman.
Cristiano - who is currently dating model Irina Shayk - plans to bring up his love child with the help of his mum Dolores.
'We don't know the mother and we've never met her,' says Katia.
'You need to ask Cristiano about that... We don't think it's strange that a man like Cristiano brings up a child on his own.
'The baby's in good health and doing very well and that's the most important thing in all of this.'
