He's alive & well. His career is still in the intensive care unit trying to recover from his inevitable soon to be one hit wonder "Gangnam Style." I don't think he will ever have another hit ever again. He hasn't yet & it already has been some time since Gangnam Style that he should have had another hit by now. I believe his career is unfortunately is evidently Rigor Mortis bound.
Naa it's an internet Hoax.
All of these false deaths are internet hoaxes. You should know that by now.
Whatever makes you fell better.
