A lawyer for the actor and comedian has said Dickinson’s claims are a "complete lie".
In an interview with Entertainment Tonight, 59-year-old Dickinson claimed that Cosby had drugged and raped her in 1982, after he invited her to visit him at a hotel in Lake Tahoe, California, where he was performing a stand-up show.
Cosby’s attorney Marty Singer told Sky News the allegations were false.
He said: "The only story she [Dickinson] gave 12 years ago in her autobiography, as well as her interviews with the media, was that she refused to sleep with Mr Cosby and he blew her off."
He added: "You can confirm with Harper Collins that she never claimed that Mr Cosby raped her, that no attorney representing Bill Cosby tried to kill the story (since there was no such story) and no one tried to prevent anything she wanted to say about Bill Cosby in her book."

Dickinson is the latest in a string of women to accuse Cosby of sexual assault. Cosby has consistently strongly denied all the previous allegations.
In October, Barbara Bowman claimed that Cosby drugged and raped her when she was a teenager in 1985, when she was then an aspiring actress.
Bowman was one of 13 women called to take to the witness stand in 2006 when Andrea Constand claimed that Cosby had drugged and assaulted her in his Philadelphia mansion in 2004.
The allegations were firmly denied by Cosby’s lawyers. In 2006, he settled the case with Constand. The terms of the settlement remain undisclosed.
At the weekend the actor’s lawyer said that he will not be commenting on the “decade-old discredited” allegations.
“The fact that they are being repeated does not make them true,” read a statement on Cosby’s website.
“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.
“There will be no further statement from Mr Cosby or any of his representatives.”Reuse content
