Stefán Karl Stefánsson (born on July 10, 1975 (1975-07-10) [age 43]) is an Icelandic film and stage actor. He is best known for playing the villain Robbie Rotten on the Nick Jr. children's television series LazyTown. He is now living in Los Angeles with his wife, Steinunn Ólína Þorsteinsdóttir, three daughters and a son.

Personal Life

Stefán was born in the town of Hafnarfjörður, Iceland, where he grew up and lived for most of his life. He moved to the United States in 2004.

Following Stefán's announcement in October 2016 that he had been diagnosed with pancreatic cancer, a GoFundMe campaign was created by LazyTown head writer Mark Valenti to pay his living costs when he fell too ill to work. The campaign was popularized by the YouTube channel SilvaGunner uploading a parody of Stefán's work, which led to the song "We Are Number One" from LazyTown becoming an internet meme. As of June 11, 2017, the campain had raised over $121,000 , surpassing its goal of $100,000. To thank contributors, Stefán held a live stream on Facebook on 11 December 2016, where he performed the song with the other actors from the music video.

On May 19, 2017, his wife announced on Facebook that his cancer had relapsed and two masses on his liver have to be surgically removed.

On June 21st, 2017, Karl's wife, Steinunn Ólína Þorsteinsdóttir posted on Facebook that the cancer has once again metastasized and has reached Stage IV, meaning that he would most likely not survive. She states in her post "Although the chances and statistics are not in our favor, and Stefán's candle burns quickly, we will not be scared of fear."
