But Green explained via Facebook that the footage was a hoax filmed as part of an upcoming video project.
"I just want to let everybody know that I am alive, that I'm well, and I'm okay. Truthfully, I'm really upset that anybody had to be emotionally disturbed by what they saw today," he said.
"What you saw today was a clip from a smaller video that we were shooting for a new project I'm doing called Gnarly Davidson. It's supposed to set up [...] and introduce the new character identity.
"I want to thank everybody for their love and support and concern."
Green had previously spoken about the project and described it as a solo mixtape that would sound similar to that of Gnarls Barkley.
"It's really cool," he said in an interview a few months ago. "It will definitely put you in the space, it's very Gnarls-esque sonically and instrumentally."
Before Green explained the situation, celebrities had started to contact him on Twitter to make sure he was OK.
And once fans found out it was a hoax, the messages of support soon turned into complaints that they'd been duped.
