Cristiano Ronaldo wants to have seven children.

The 32-year-old footballer's girlfriend Georgina Rodriguez is expecting the star's fourth child following the recent birth of the Real Madrid ace's four-week-old twins Eva and Mateo via a surrogate, and he revealed his seven-year-old son Cristiano Jr. is keen for more siblings.

In an interview with Chinese TV reported in Portuguese newspaper Correio da Manha, he said: ''Cristianinho is very happy.

''He's doing well and says he wants more brothers and sisters. He wants seven, the magic number, and I think that's good.''

Ronaldo is known to be a huge fan of the number seven having named his fashion brand CR7 after his initials and his squad number for Real Madrid and his former team Manchester United.

Earlier this month, the soccer superstar confirmed his 22-year-old girlfriend was expecting following speculation.

When asked if he was excited about his next impending arrival, he said: ''Yes, very much.''

While the star can do just about everything on a football pitch, he admitted changing nappies is not one of his strengths but he gives it his best shot.

Quizzed about how he gets on changing diapers, he replied: ''I'm not very skilled at that, but I try.''

Ronaldo is a keen Instagram user and last month he took to the site to show off a picture of himself cradling his twins.

He added the caption: ''So happy to be able to hold the two new loves of my life''

Speaking about Eva and Mateo, he recently said: ''They are precious, I am delighted. Yes I am, I'm very happy.''
