Netflix has decided to postpone its Bill Cosby special as the comedian faces several accusations of assault and rape.

"At this time we are postponing the launch of the new stand up comedy special 'Bill Cosby 77'," a Netflix spokesman said on Tuesday.

In an interview to Entertainment Tonight that aired on Tuesday, former supermodel and TV host Janice Dickinson claimed that Cosby had drugged and raped her in 1982.

Dickinson also revealed that she wrote about the assault in her 2002 autobiography, but Cosby and his lawyers pressured her and the publisher to remove the details.

"I'm doing this because it's the right thing to do, and it happened to me, and this is the true story," she said.

Netflix's stand-up comedy special was set to air on November 28 in honour of the Emmy winner's 77th birthday.

Cosby's appearance on CBS' 'Late Show With David Letterman' was recently cancelled. The comedian was also starring in an upcoming NBC comedy, although that project is looking less likely to move forward.

His lawyer recently issued a statement saying "Mr. Cosby does not intend to dignify these allegations with any comment. He would like to thank all his fans for the outpouring of support and assure them that, at age 77, he is doing his best work."
