Absolutely devastating news from Cristiano Ronaldo and longtime GF Georgina Rodríguez ... the couple just announced their baby boy -- a twin -- tragically passed away.
Ronaldo and Rodríguez had been expecting twins.
Cristiano made the crushing announcement on Instagram Monday morning ... and it's difficult to read.
"It is with our deepest sadness we have to announce that our baby boy passed away. It is the greatest pain that any parents can feel," the 37-year-old soccer star wrote.
"Only the birth of our baby girl gives us the strength to live this moment with some hope and happiness."
The details surrounding the tragic incident are not clear.
Remember, Cristiano and Georgina announced they were expecting twins in October. Then, they shared their gender reveal in December (with help from the whole family) ... when they found out they were expecting a boy and a girl.
Cristiano ended his post thanking the medical professionals who helped his family.
"We would like to thank the doctors and nurses for all their expert care and support. We are all devastated at this loss and we kindly ask for privacy at this very difficult time."
