InstagramCelso Santebañes, the Brazilian-born man who earned the nickname Human Ken Doll, has passed away after a five-month battle with leukemia.
According to Yahoo! Brasil, the 21-year-old died from bacterial pneumonia which was reportedly brought on by his blood cancer.
Santebañes passed away on Thursday at the Federal University of Uberlândia Clinical Hospital in Brazil, where he was undergoing chemotherapy.
After spending tens of thousands of dollars to transform himself to look like a real-life version of Barbie's iconic boyfriend, Santebañes quickly garnered attention for his larger-than-life looks.
He first discovered that he had cancer after he visited a hospital to treat an infection following a procedure where hydrogen fillers were injected into his legs.
Earlier this year, the media personality took to Instagram to explain his diagnosis in a video showing him in a hospital bed with an IV.
"I've cried…I see my world collapsed, I do not want anyone to pity me, just pray for me and respect me," he shared in the caption, which has been loosely translated from Portuguese.
"I am starting chemotherapy and I admit I'm a little concerned about some side effects, like hair loss, nausea, my body's rejection [of chemotherapy], among other things, but I am no longer concerned with the issue of aesthetics. For me that doesn't matter. What matter is my health now, and I will fight for it."
Rest in peace, Celso Santebañes. Our thoughts go out to his family and friends during this difficult time.
