The 29-year-old model - who is now dating Bradley Cooper - has revealed how ''stupid'' she felt when the 30-year-old football player confessed to her on New Year's Eve, after five years together.
Irina told a source close to the pair: ''Now I know the truth and I feel completely betrayed. I trusted him and stuck up for him when there were rumours he had been with other women. I feel stupid that Cristiano has fooled me.''
The relationship began to unravel as the pair planned a party at their Madrid home when Irina spotted one of Cristiano's phone statements lying around and spotted numbers she didn't recognise, so checked them using messaging apps and discovered they were attached to profiles of women from all over the world, including Colombia, Australia and France.
The source told The Sun newspaper: ''Irina could not believe it. She felt she had been completely betrayed. She immediately confronted Cristiano about it, but he initially denied any knowledge. After she explained to him what she had found he eventually admitted to messaging the girls.
''He gave little excuse. She couldn't believe it so immediately got out of the house. She ended the relationship there and then.''
