Claudio Coelho has claimed in a reality TV show in Portugal by telling fellow guests on Portuguese show Casa dos Segredos (House of Secrets) that Ronaldo got furious after he found out her sister Katia romped with him in the Portuguese skipper's bed room
“It is normal for Cristiano not to like other people occupying his personal space, Claudio Coelho said
“I understand him fully.
“But the problem is that his sister has little judgment, despite being almost 40-years-old.
“Katia and I were visiting the Geres area, and spent the weekend at Ronaldo’s house.
“That was where we slept together for the first time.”
He added: “It is not the first time she and Ronaldo have fallen out.
“While we were together he was angry with her for going on a reality TV show in Spain.”
Reports in Portugal had also claimed Cristiano had cut off contact with Katia after she starred in the reality show called Survivor.
But last night she insisted: “I am very grateful to my family and especially my brother.
“I know that, unfortunately, there are many families and many brothers who do not speak, but fortunately, that is not the case with me.
“I am as important to them as they are to me.”
