Christie Brinkley has reportedly filed suit against ex-husband Peter Cook for breaching the confidentiality agreement in their divorce settlement.
During a candid interview with Barbara Walters on a U.S. news show 20/20 last week (10Oct08), Cook spoke of his regret of the affair that ended his marriage.
The interview reportedly angered Brinkley, who failed in her attempt to secure a restraining order against Cook just prior to its airing - which would have prevented him contacting the couple's two children.
Brinkley claimed that by opening up about their marriage problems, he violated the confidentiality provision set out in the terms of their divorce, which was agreed upon following a bitter public trial over the summer (08).
Cook could be subjected to a $10,000 (GBP5,405) contempt of court fine if he is found to have violated the terms of the deal, according to the New York Post.
Brinkley could also be allowed to respond to his allegations.
But Cook has defended his decision to open-up about his failed marriage on the news programme, telling the newspaper: "Anything I've done to resurrect my image for the sake of my children she finds offensive... It's clear that she's threatened by my relationship with them. Really, I just want her to leave us alone."
Cook has also countered that Brinkley has "multiple breaches of the agreement" herself.
His lawyer, Steve Kuhn, insists his client's on-air comments did not constitute a breach of the confidentiality agreement.
Brinkley's lawyer, Robert Stephan Cohen, was unavailable for comment.
