Los Angeles, Feb 18 (IANS): Rapper Kanye West has hit out at singer Taylor Swift, calling her a "fake a**" backstage at "Saturday Night Live", according to a new audio footage.

In the clip released by pagesix.com, the "Gold digger" rapper can be heard complaining about changes that were made to his set, and he can be heard taking digs at Swift. 

"Look at that shit, they took my f**kin' stage off of SNL without asking me. Now I'm bummed. That and Taylor Swift, fake a**," he says in the recording.

This is not the first tine West has used explicit vocabulary against Swift.

He also released a song "Famous", which contains the line: "I feel like me and Taylor might still have sex / Why? I made that bitch famous." 

West claims Swift approved the lyrics, which she and her team have denied.

In the SNL audio, West, who went on to perform "Ultra light beams" and "High lights" during the February 13 show, then claims he is "50 percent more influential" than a slew of famous names.
