Cristiano Ronaldo split with girlfriend Irina confirmed by model's agent

Irina Shayk is now officially back on the market according to her agent.

Reported in the New York Post, Shayk's representative commented on the break up: 'We can confirm that Irina Shayk has ended her relationship with Cristiano Ronaldo.'

It is not yet clear what caused the split, with rumours circulating of a rocky relationship between the Russian model and Ronaldo's mother. 

The agent added: 'She has been very close to his family throughout their relationship. Any negative rumors about Irina and Ronaldo's family are completely false and have not been a factor in the cause of the split. Irina has no comments at the moment.' 

Shayk refused to attend the 60th birthday party of the Ballon d'Or winner's mother according to a newspaper in Portugal.

Coreio Manhana reported that Shayk had told Ronaldo that she would not be attending the bash in his native Madeira, and the ensuing row served to end the pair's five-year romance.  

As a parting dig to Ronaldo, the Russian model has now stopped following him on Twitter.

A source told Coreio de Manhana: 'Cristiano wanted to surprise his mum and as he spent Christmas with Irina in Dubai, he had planned to be with his mum on her birthday, but Irina didn't want to go.

'They had such a big row that he ended up spending New Years Eve alone with his son.

'Irina mouthed off about Dolores and Ronaldo took sides with him mum. It was the straw that broke the camel's back because they had hadn't been getting on well in the last few months.'
