Former Manchester United star Cristiano Ronaldo allegedly cheated on his Russian girlfriend Irina Shayk, which led to their break-up.

The 29-year-old Victoria's Secret model had split from the 30-year-old Real Madrid star this January.

According to the Sun, the supermodel found messages on his phone from "dozens of women."

"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," Shayk told a source, close to her.

Shayk reportedly discovered numbers on his phone statement that belonged to women across the world, including Colombia, Australia and France.

"She immediately confronted Cristiano about it, but he initially denied any knowledge," the insider revealed. "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."

Rumours that the couple have split started after Shayk unfollowed him on Twitter. She did not come to support Ronaldo when he was honoured with the prestigious Ballon d'Or title for the third time, at a ceremony held in Zurich, Switzerland.

Recently, Shayk also removed Ronaldo's images from her Facebook, Twitter and Instagram accounts.
