AN 11-year-old actor has died after suffering 21 cardiac arrests.

On Wednesday, Milena Brandão, a Brazilian actress and former child model, was admitted to the hospital due to intense headaches. Unfortunately, she passed away just two days afterward.

Thays shared with her daughter’s Instagram 196,000 followers the news of her passing on Friday in an emotional post:

“The memories we spent together will remain in my memory and I’ll never forget your joy that was contagious to everyone around you.

“My girl, I’m already missing you not being here and I know I’ll miss you even more in the days to come.

“You were the light in our lives and I know that from up there you’ll continue to watch over us and light up our lives.

“And I’ll love you forever, and you’ll always be in my heart.”

Milena, who died at the Grajaú General Hospital in São Paulo, Brazil, gained recognition for her role in the soap opera, The Childhood of Romeo and Juliet.

Her followers have been left devastated by the news of her death.

One user wrote: “My God, what a pain. How sad. As a mother, my heart bleeds.”
