Steinunn Olina Thorsteinsdottir responded to the death of her husband, actor Stefan Karl Stefansson, after he died Tuesday. She took to Facebook to reveal the tragic news.

"My beloved, Stefan Karl Stefansson, 43, has passed away after battling aggressive bile duct cancer for two years," she wrote, along with his birth (July 10, 1975) and death dates.

"Per Stefan's wishes, there will be no funeral. His earthly remains will be scattered in secrecy in a distant ocean," she continued. "Stefan's family wants to express their gratitude for the support and warmth received in recent years, and to express their deepest sympathy to the many friends and fans of Stefan Karl."

Stefansson, who was best known for his role as the villain, Robbie Rotten, on the Nick Jr. series LazyTown from 2002 to 2014, revealed his cancer battle on Reddit in 2016. "My family and I have only had under a month to get used to the idea of me having cancer," he said. "My wife and I have had long talks about the situation and we are realistic about all possible outcomes."
