Peter Cook Speaks Out About Christie Brinkley Divorce
10/07/2008 AT 08:25 PM EDT
"I'm not the ... pervert that I've been painted to be," Cook tells Barbara Walters in an interview that will air Friday on ABC's 20/20.
Asked why he was speaking out now, Cook, 49, who admitted to having an affair with an 18-year-old assistant and an online pornography habit, tells Walters, "The misinformation that came out during the trial is the elephant in the room. It's the elephant in the room for my kids."
During the marriage, he says, "I wanted a little acknowledgment, a little attention, a little thank you every now and then for my efforts, for the amount of time I took to care for her and my family, for the wealth I was building. Just the tremendous amount of work I was putting into my family. ... My world became her world. It had to be that way."
The 54-year-old supermodel's lawyer, Robert Stephan Cohen, released a statement Tuesday saying that Cook may face additional legal action for speaking out about the case.
"It is shocking that Mr. Cook, after having his day in court, would continue this firestorm created by his bizarre behavior by violating an agreement and court order that prohibits either party from discussing their marriage or divorce in any public way," Cohen says. " Ms. Brinkley plans to pursue her legal options arising from his gross disregard of the children and the court order.
