Listen to Kanye West Blast 'Fake-A**' Taylor Swift in Leaked 'SNL' Backstage Recording

A source says Kanye was not yelling at SNL staff and did not know he was being recorded.

It seems Kanye West had a moment while backstage at Saturday Night Live this weekend.

A source close to the 38-year-old rapper told ET that West threatened to walk off the program when he found out that part of his set had been taken down before showtime, and now, new audio obtained by Page Six appears to reveal some of the behind-the-scenes venting that transpired.

The audio clip below contains explicit language.

In the one-minute clip, West calls Taylor Swift a "fake-a**," before lamenting the comedy variety show for the set changes.

"Look at that s**t, they took my stage off of 'SNL.' Without asking me. Now I'm bummed," West can be heard saying. "I went through six years of this f**king s**t."

“Are they f**king crazy?" West adds, claiming that he's "50 percent more influential than any other human being... Dead or alive."

"Stanley Kubrick, Picasso, Apostle Paul, f**king Picasso and Escobar," the rapper says.

But a source close to West tells ET, "He did NOT yell at SNL staff. This audio was secretly recorded while he was venting his frustration in a private moment with his team."

"He found out his stage design was changed and taken apart under the direction of the show's lighting director without anyone's approval," the source adds. "He had spent an entire day rehearsing and a lot of hard work into the performance. Dramatic set changes were made 30 minutes before going live."

"It should be understandable why he was upset after being completely blindsided," the source continues.

The source also notes: "Kanye was seen hugging [SNL creator] Lorne Michaels just before the goodnights, and he stayed afterwards to chat with the staff and the cast, and thanked the producers on his way out the door."

The source also mentioned that the show producer's were very "apologetic" about the situation.

Meanwhile, on Wednesday, West shared a moment of humility on Twitter, tweeting, "My number one enemy has been my ego."

"A wise man should be humble enough to admit when he’s wrong and change his mind based on new information," West said in another tweet.

West's critically-acclaimed new album, The Life of Pablo, is streaming now via Tidal on the rapper's website.
