Bill Cosby has been ordered to submit to a deposition in the ongoing defamation suit filed against him by former "America's Next Top Model" judge Janice Dickinson.

According to Deadline, on Monday LA Superior Court judge Debra Weintraub ordered the beleaguered comedian and his former attorney Martin Singer to make themselves available for interrogations by attorneys for Dickinson by Nov. 25.

Dickinson is one of more then 50 women now accusing Cosby of drugging and sexually assaulting them over a period that spans more than four decades and started in the 1960s. Up until about two weeks ago, Singer had served as Cosby's primary attorney in all the cases.

Dickinson's defamation claim stems from denials and statements made last year by representatives of Cosby, including Singer, branding her accusations as false and labeling her story a total "lie."

Christopher Tayback of Quinn Emanuel Urquhart and Sullivan replaced Singer as Cosby's attorney last month and was in court on his behalf on Monday, along with his colleague Justin Griffin.

"We are very pleased with the court's careful and thoughtful ruling on the depositions of Mr. Cosby and Mr. Singer," Dickinson's attorney Lisa Bloom told reporters following the hearing. "It was the right ruling."

 Bloom later confirmed she will personally be conducting the interrogations herself.

The deposition marks the second time Cosby will have had to submit to such a grilling in less than a month. Back in October, famed civil rights attorney Gloria Allred quizzed him for more than seven hours in Boston on behalf of her client Judy Huth, who has also sued Cosby for defamation.

The findings of those proceedings could become public as soon as Dec. 22, depending on a judge's ruling on whether the matter should be made public.

Cosby has denied all the accusations and has never been criminally charged in any of the cases.
