Joan Rivers' rep says voice not comedian's on recording

A tape purported to feature Joan Rivers' voice is a fraud, says a rep for the late comedian.

On Tuesday, the New York Post's Page Six ran a story about Rivers doing an audio take of a promo for Brad Zimmerman's upcoming off-Broadway show, "My Son the Waiter, a Jewish Tragedy." In the clip, posted on YouTube, the person on the recording complains about issues with her voice.

But a rep says the voice on the recording is not Rivers' track. She released a statement to Page Six: "The recording is a fraud. Joan never made any such tape. 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."

Zimmerman was Rivers' friend and occasional opening act.

Rivers was hospitalized on Aug. 28 after she went into cardiac arrest during the procedure. She died on Sept. 4 at age 81. The New York state health department is investigating the circumstances. Dr. Lawrence Cohen, the medical director where Rivers underwent her procedure, is no longer working at Yorkville Endoscopy.

Rivers was remembered at a star-studded funeral in Manhattan attended by family and many celebrity friends, including Hugh Jackman, Sarah Jessica Parker and Whoopi Goldberg.

On Monday, Jerry Seinfeld revealed that Rivers was going to be a lead guest on the new season of his series "Comedians in Cars Getting Coffee."
