Sharon Stone has paid tribute to her 11-month-old nephew, who has died after suffering total organ failure.
The actress, 63, shared the news on Instagram after telling fans last week River Stone was critically ill and the family was praying for a miracle.
She said River, the son of Stone's brother Patrick, died on Monday, as she shared a touching video tribute featuring footage of the little boy smiling while playing in bed.
