Supermodel Irina Shayk has fuelled rumours suggesting she has split from soccer ace boyfriend Cristiano Ronaldo by 'unfollowing' the sportsman on

Portuguese star Ronaldo reportedly dumped his girlfriend of five years after she refused to attend his mother's surprise 60th birthday party in Madeira after spending Christmas with her man in Dubai, United Arab Emirates.

As a result, the soccer star spent New Year's Eve (31Dec14) alone with his son.

Shayk also missed Ronaldo's third Ballon d'Or ceremony on Monday (12Jan15).

Neither Shayk nor Ronaldo have commented on the split rumours.
