Ronaldo's No Womaniser

Cristiano Ronaldo's mum says that her son is not a womaniser, as a matter of fact, she has only met two of his girlfriends.
If I am correct, just because she has only met two of them, it doesn't mean that he isnt a womaniser. Ronaldo has been pictured with many women, ages ago he was photographed with Gemma Atkinson but his mum said that he didn't know her and had never met her.

Personally, I can't believe that he isn't a womaniser, anyway, here is what Dolores has had to say: “My son has only introduced two girlfriends to me – Merche Romero and Nereida Gallardo.
“If I believed what other people say, he has been with more than 100 and he is a womaniser.
“But I know that it is not true. When he likes a girl and the relationship is serious, he presents her to his family.”
