Russian model Irina Shayk has indicated that her relationship with Real Madrid forward Cristiano Ronaldo ended because he was unfaithful.

The 29-year-old called time on her five-year relationship with the Portuguese international earlier this year, with Playmate Daniella Chavez and Brazilian model Andress Urach both rumoured to have been involved with the Ballon d'Or winner while he was still dating Shayk.

Shayk told Spanish magazine Hola: "Of course I prefer to be with someone, but with the right someone. He's got to be kind, amusing and honest and he's got to know how to treat a woman. And he's also got to be faithful.

"My ideal man is faithful, honest and a gentleman who knows how to treat women. I don't believe in men who make us feel unhappy, because they're boys not men. I thought I had once found the ideal man but it didn't turn out that way.

"I think a woman feels ugly when she's got the wrong man at her side. I've felt ugly and insecure. If you stay with someone it's because you're walking in the same direction and you're both looking for the same thing. Both should share the same concept of what a relationship means and the same energy to believe in a monogamous relationship."

Shayk has been photographed on dates with American actor Bradley Cooper since separating from Ronaldo.
