In audio obtained by Page Six, the furious rapper, who threatened to walk off the show after his set was altered at the last minute, can be heard yelling at production staff and also lashes out at Taylor Swift once again.

"Look at that s**t, they took my f**king stage off of SNL without asking. Now I'm bummed," he fumes. "That and Taylor Swift — fake a**."

Continuing, he says: "Now if I'm going to do this, we're breaking the motherf**king internet. I went through six years of this fucking s**t."

"Are they f**king crazy. Bro, by 50 percent. Stanley Kubrick, Apostle Paul, Picasso, f**king Picasso and Escobar. By 50 percent more influential than any other human being."Don't f**k with me. Don't f**k with me. Don't f**k with me. By 50 percent dead or alive. By 50 percent for the next thousand years. Stanley Kubrick, Ye..."

Meanwhile, a source told Entertainment Tonight following the incident: "This is the seventh time Kanye West has appeared on SNL, they know he is very particular."

The SNL lighting director/designer, on his own, decided to dismantle half of Kanye's set because he didn't like it. The set was dismantled in a way it couldn't be put back together on time.

Kanye found out 30 minutes before showtime that this had happened. "Kanye was very upset about the situation, and did threaten to walk off the show," they added.

Mirror Celebs has contacted a rep for Kanye for comment.
