A raspy YouTube video has surfaced that some media outlets are reporting is one of the final recordings of Joan Rivers. In the audio, the voice can be heard complaining “My voice has been bothering me. I don’t know what it is.” A rep for the late TV icon is adamant the recording is a fake.

"The recording is a fraud," her rep told FOX411. "Joan never made any such tape."

Rivers, who was by no means slowing down when it came to her career, died on Sept. 4 at the age of 81 after she suffered complications following a medical procedure at a New York City clinic.

The audio posted on YouTube, titled “Joan Rivers [sic] Last Session” is supposedly a meant to promote the play “My Son the Waiter, a Jewish Tragedy,” starring Brad Zimmerman.

"This is a publicity stunt that was created by Brad Zimmerman and his public relations representative, Beck Lee, and is wholly disrespectful to the memory of Joan Rivers," Rivers' rep charged.

    A coughing voice can be heard saying, “I told [you] I didn’t feel good. My voice has been bothering me. I don’t know what it is … I feel like s- -t. I’m tired already.”

    The YouTube account that posted the video is titled “Brad Mysonthewaiter” and has only ever posted one video. No information about the account is posted in the “About” section on YouTube.

    A rep for Zimmerman did not immediately return FOX411’s request for comment about the authenticity of the recording.
