Christie Brinkley's ex-husband Peter Cook is at the centre of a sex tape scandal - his former mistress is considering legal action over an alleged sex video uncovered weeks after he finalised his divorce from the model.
Brinkley and Cook split in 2006 after 10 years of marriage following Cook's affair with his then 18-year-old assistant, Diana Bianchi.
The former couple reached a settlement after a bitter public divorce trial over the summer (08).
Over the course of the trial, testimony included revelations of Cook's alleged $3,000 (GBP1,620) monthly porn habit and details of his affair - including a $300,000 (GBP162,160) payout to Bianchi to persuade her to keep the details of their relationship private.
Rumours of an explicit home video showing the architect having sex with Bianchi were reported throughout the trial, although no such tape was uncovered.
But the New York Post has now unveiled a series of stills, reportedly taken from the alleged sex tape, which apparently depict the pair having sexual intercourse on a brown love seat.
According to the newspaper, Bianchi performs a striptease for Cook, who is alleged to have recorded the tape at his Southampton, New York architectural office without Bianchi's knowledge.
Additional stills not taken from the video reportedly reveal Bianchi willingly posing topless.
Bianchi's lawyer, Joe Tacopina, says: "We are now going to review, and begin weighing our legal options, for Diana."
And Brinkley insists she has no knowledge about the alleged video.
Her lawyer Robert Cohen says: "Nothing about Peter Cook's behavior shocks us. We don't know anything about this tape. We never saw it and we never heard about it. Christie's concern is for the sake of her children and she hopes this video is kept private."
A spokesperson for Cook has declined to comment.
His divorce with Brinkley was finalised in Suffolk County, New York on 3 October (08).
