Daddy Ronaldo

Cristiano Ronaldo has announced to the world (on Twitter - doesn't everybody announce the key moments in their lives this way?) that he is a father. Apparently he has exclusive custody of the child, which was born of an anonymous surrogate mother. Cristiano's sister says the baby is the spitting image of his father (hmm, has he started posing and diving already then?)
The strangest thing about this story is that Ronaldo managed to keep it secret for so long...
