It's been four months since Irina Shayk confirmed her separation from longtime love Cristiano Ronaldo, and new report has just surfaced that she dumped him because he cheated on her. She reportedly found messages on his phone from "dozens of women."

"For so long she trusted him and stuck up for him but now she feels completely let down and betrayed," The Sun quoted a source as claiming. "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," the source added. The Sports Illustrated Swimsuit model reportedly told one source close to her and the soccer stud, "Now I know the truth and I feel completely betrayed. I trusted him and stuck up for him when there were rumors he had been with other women. I feel stupid that Cristiano has fooled me."

Following her separation from Cristiano in January after five years of dating, Irina has been romantically linked to movie hunk Bradley Cooper. The new lovers have been spotted packing on PDA on several occasions. They were last seen sharing passionate kiss in London last week.
