Portugal forward Cristiano Ronaldo and his partner Georgina Rodriguez, who announced in October last year they were expecting twins, said on Monday one of the two babies has died.

"It is with deep sadness we have to announce that our baby boy passed away," Ronaldo and Rodriguez said in a joint statement on social media. It is the greatest pain that any parent can feel.

"Only the birth of our baby girl gives us the strength to live this moment with some hope and happiness," they said.

Asking for privacy during this difficult time, the couple thanked the doctors and nurses for their expert care and support.

The 37-year old Ronaldo, five-times world player of the year, rejoined Manchester United last year after winning multiple trophies with Real Madrid and Juventus. (Reporting by Catarina Demony; Editing by Ed Osmond)
