The star, 28 — a footballing role model who is also an ambassador for Save the Children — contacted Andressa out of the blue after being passed her number by a mutual friend last month.

Saucy snaps had just emerged of her snogging fellow model Camila Vernaglia, 21, who had finished second in the Brazilian competition known as Miss BumBum.

Ex-Manchester United idol Ronaldo — who famously winked at the Portuguese team bench after England pal Wayne Rooney’s 2006 World Cup red card — began sending Andressa texts and later spoke to her via internet service Skype.

Andressa said: “I have always thought Cristiano Ronaldo is one of the most gorgeous men in the world, so I couldn’t believe it when he got in touch with me.”

“He said he was very excited by my pictures online and one of the first things he asked was if I really was a Miss Butt Brazil model.

“He knows Brazilian women have some of the best butts in the world, so he was very impressed by that! We exchanged texts and spoke a few times.

“He wouldn’t stop making comments about my butt. He wanted to know if it was all natural which — of course — it is.

“He called me ‘little horse’ and told me he had ‘dreamed of that bum last night’.”

She recalled: “Cristiano Ronaldo told me to come to Madrid and that we’d meet, but he would not tell me where or when exactly.

“He said he had to be careful because if it came out that he’d seen me, his girlfriend wouldn’t be happy. They are together, but he told me the relationship wasn’t serious. He didn’t say anything else about her.”

Andressa told how the pair finally met at the city’s Villa Magna hotel, where suites cost up to £12,500 a night.

She took a taxi there and waited in the lobby — hoping Ronaldo would meet her and escort her upstairs. But instead he arrived separately in a grey Audi R3, pulled into the underground car park, and took a private elevator to the sixth floor.

Seconds later Andressa received a text telling her his room number.

When she got there, she said: “We looked at each other and, just like that, we were all over each other. He is fantastic.

“It was incredible — the best time of my life. His body is perfect, like something from the gods.

“He is so ripped — there isn’t an ounce of fat on his body.

“I can barely believe it. I have never been with anyone like him.

“He smelled like heaven and kept going for hours. And, yes, he is very ‘gifted’.” Andressa added: “He could not stop talking about my butt. He was obsessed.”Afterwards, Andressa claimed Ronaldo demanded she wait in a public area of the hotel before texting her to say he had to leave.

She went on: “I was a little annoyed. I walked out of the front entrance for a cigarette and a security guard immediately grabbed me and took me back inside, saying photographers were outside.

“Cristiano then texted again, he told me to go back up to the room as he had something to tell me.
