(CNN) Attorney Alan Dershowitz has countersued a woman who claims he sexually abused and defamed her, claiming she defamed and intentionally inflicted emotional distress on him.

The woman, Virginia Giuffre, formerly known as Virginia Roberts, says she was a victim of multimillionaire alleged pedophile Jeffrey Epstein, and that Dershowitz had sex with her. Epstein died in August while awaiting trial on sex trafficking charges; the New York City medical examiner determined he had died by suicide

Dershowitz claims Giuffre "conspired with her lawyers to publish her false and defamatory claims of and concerning Dershowitz with a knowing or reckless disregard of their falsity," according to the lawsuit. "She has done so with the specific intent and design that her statements be a source for the media so that the media will publish her false allegations of and concerning Dershowitz that he had sex with her while she was underage as part of Epstein's criminal sex trafficking of minors."

Dershowitz adds in the lawsuit that "Giuffre has falsely and with a knowing and reckless disregard of falsity and acting out of ill-will and spite publicly labelled Dershowitz as a child rapist and molester."

The suit shows that Dershowitz "is ready to aggressively defend against the allegations made against him and press forward with his own claims against Ms. Giuffre for the campaign of defamatory and tortious conduct she has waged against him," one of his lawyers, Arthur Aidala, said.
