More famous faces are distancing themselves from Bill Cosby following allegations of sexual assault against him. Publishing company Simon & Schuster has pulled celebrity blurbs praising Cosby from online retailers selling a 2014 biography on the comedian's life.

The blurbs, penned by David Letterman, Jerry Seinfeld, Billy Crystal, Mary Tyler Moore and Stephen L. Carter prior to Cosby's scandal breaking are featured on the back of the book Cosby: His Life and Times.

"Whenever I think of why my life as a comedian happened, the first name I think of is Bill Cosby," Seinfeld's blurb read. "I know certain religions forbid idol worship. If anyone ever told me I had to stop idolizing Bill Cosby, I would say, 'Sorry, but I'm out of this religion.' So, if you want to join the Religion of Cosby, as I did back in 1966, Mark Whitaker's wonderful new book would be our Bible."

Spokespersons for both Seinfeld and Letterman spoke out, saying, "We were unaware that those quotes were still in circulation and are asking the publisher to refrain from future use."

The biography's author, Mark Whitaker, sat down with ET last year before the flood of sexual assault allegations came out against Cosby. The veteran journalist and former Executive Vice President and managing editor for CNN Worldwide revealed Cosby was unlike anyone he'd ever interviewed.

"He never really answers your questions," Whitaker said. "He just starts telling stories, and you have to go with it."

Interestingly, Cosby did not dodge questions about the woman who claimed to be his love child, Autumn Jackson. While Cosby admitted to having an affair with Jackson's mother in the '70s, the paternity has been disputed.

"He was very honest about what happened," Whitaker said. "He actually said in the interview, 'I don't want to be seen as another entertainer who just passes the buck and says, 'Everybody does it' ... 'I want to be remembered,' he said, 'As someone who's willing to take the hit.'"

Despite allegations of sexual assault from more than two dozen women, Cosby has not been criminally charged and maintains his innocence.
