The hits keep on coming from Peter Cook, it seems. Less than a week after his highly controversial interview with Barbara Walters on 20/20, Christie Brinkley‘s ex-husband is now embroiled in a new scandal – the alleged existence of a sex tape featuring a romp between him and mistress Diana Bianchi.


However, Diana’s lawyers are now hitting back at the steamy video rumors.


In an statement obtained by Extra, Diana’s attorney, Rosemarie Arnold responds to the reports of the tape saying, "Whatever tape is out there it was recorded surreptitiously without her consent.  My partner Joe Tacopina and I are reviewing Diana’s legal options.  Mr. Cook can sit with Barbara Walters and claim to be a lamb but he is still a wolf.”


Peter and Christie’s divorce just became final, after months of legal wrangling and a bitter back and forth custody battle. Peter has admitted to spending thousands of dollars a month on Internet porn, as well as cheating on Christie with Diana, who was 18 at the time.
