Ronaldo's sister posts emotional message after tragic death of his baby son

Cristiano Ronaldo's sister Katia Aveiro has posted an emotional open letter to her brother on Instagram after the tragic death of his baby son.

"Our little angel is already on daddy's lap," wrote Katia, in reference to their father Dinis who died of liver failure in September 2005. She added: "I love you and my heart is with you over there. May God take care of you and strengthen your path more and more.

"Our little girl is there firm and strong and full of health and is going to show us with every day that only love matters." Katia posted the message alongside pictures of Georgina and Cristiano with her two children.

Ronaldo announced on social media on Monday evening that his twin son had passed away as his daughter was born.

The Portugual international wrote: "It is with our deepest sadness that we announce the passing of our baby boy. It's the greatest pain any parent can feel. Only the birth of our baby girl gives us the strength to live this moment with some hope and happiness.

"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.

"Our baby boy, you are our angel. We will always love you. Cristiano Ronaldo and Georgina Rodriguez."

The devastating news comes just a few weeks after Georgina had posted a touching tribute to Ronaldo as the couple eagerly awaited their new arrivals.

She wrote on Instagram: "Every day by your side is happy and special. We love you indefinitely. Thank you so much to the best dad in the world."
