Former Manchester United star Cristiano Ronaldo reportedly split from his Russian girlfriend Irina Shayk after she refused to attend his mother's 60th birthday party.

According to Portuguese newspaper Coreio de Manhana, the 29-year-old supermodel's relationship with Ronaldo's mother, Maria Dolores dos Santos Aveiro and sisters Katia and Elma has been sour since sometime.

"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," a source said.

"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 his 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," the insider added.

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.

Ronaldo, who has been dating Shayk since 2010, did not mention her in his acceptance speech as well.

"Dolores thinks Irina wasn't the right woman for Ronaldo's son," the source continued. "She wanted someone who would, in the future, assume the role of mum for Cristiano Jr. That wasn't a priority for Irina."
