Model Janice Dickinson is suing Bill Cosby for defamation over denials by the veteran comedian's representatives after she accused him of raping her in 1982.

Dickinson's lawsuit seeks unspecified damages on defamation, false light and intentional infliction of emotional distress claims.

It states she has been re-victimised and her reputation has suffered because of pointed denials by Cosby's lawyer that the comedian drugged and raped her in a Lake Tahoe, California, hotel room more than 30 years ago.

The allegations were first made in an interview with Entertainment Tonight last year after numerous other women accused Cosby of drugging them and inappropriate sexual conduct dating back several decades.

The lawsuit says Dickinson, 60, sought a retraction of the denials from Cosby, 77, but the request was denied.

Cosby's lawyer Martin Singer called Dickinson's rape allegations "false and outlandish".

The lawsuit details Dickinson's claims that Cosby raped her after giving her wine and a pill in the hotel room, and how she wanted to go public with her story in a 2002 autobiography, but was prevented from doing so by the book's publisher.

She did not report the incident to police in the early 1980s out of fear of retaliation by Cosby, her lawsuit states.

"This is Janice Dickinson's chance for justice," her lawyer Lisa Bloom said.
