Manchester United star Cristiano Ronaldo revealed in an Instagram post Monday that one of his twin babies with partner Georgina Rodriguez died after birth.

The Portuguese soccer star, 37, had announced he and Rodriguez, 28, were expecting twins — a boy and a girl — last fall.

He expressed the couple’s pain of losing their son on Monday. Their baby girl survived.

“It is with our deepest sadness we have to announce that our baby boy has passed away,” the couple’s message reads. “It is the greatest pain that any parents can feel.”

“Only the birth of our baby girl gives us the strength to live this moment with some hope and happiness,” the note continued. “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.”

The message concluded with, “Our baby boy, you are our angel. We will always love you.”

It is unclear when Rodriguez gave birth.

The Portugal international, 37, is the father of five other children, twins Eva Maria and Mateo, eldest son Cristiano Jr., Alana Martina and the unnamed newborn.

Manchester United tweeted: “Your pain is our pain. Sending love and strength to you and the family at this time.”

Teammate Marcus Rashford wrote his regards, by tweeting, “Thoughts are with you and Georgina brother I’m so sorry.”
