Christie Brinkley's divorce case has settled as soon-to-be ex-husband Peter Cook, battered by trial testimony about adultery and Internet porn-viewing, gave up his fight for custody of the couple's two children.

The settlement, announced after five days of salacious testimony in Suffolk County (N.Y.) Supreme Court, vindicates Brinkley's decision to oppose conducting the trial behind closed doors. With the media gleefully reporting every courtroom revelation, the spotlight almost certainly became too much for Cook to bear.

Cook went into the trial last week claiming that Brinkley is a scorned, vengeful woman who was risking their children's well-being by allowing media coverage. But any remaining hope he may have entertained of making that claim stick probably evaporated with the testimony of a psychiatrist on the fourth day of the trial.

Dr. Steven Herman testified July 8 that Brinkley should be granted custody of the children -– Jack, 13, and Sailor, 10 –- and delivered his clinical opinion that Cook “is characterologically a narcissist. While most people need a feeding for their egos, Mr. Cook has an insatiable appetite.”

Things could have gotten even worse for Cook on Day Five of the trial July 9 when two private investigators hired by Brinkley to find evidence of his indiscretions were on the witness list. Tyrone and Stephen Dux, who are twin brothers, said they were ready to introduce damaging information and photographs of Cook into evidence.

But before the Duxes could take the stand, the parties entered into settlement negotiations that culminated in an agreement early today.

Under the agreement, Brinkley gets full custody of the children and keeps 18 properties in the Hamptons that were in dispute while Cook gets $2.1 million and parenting time. “I'm very pleased with the results today,” the former supermodel said. “I was here fighting for custody.”

The children's attorney, Theresa A. Mari, requested that the courtroom be closed during proceedings related to the child custody issue. Cook supported the motion, but Acting Supreme Court Justice Mark D. Cohen said Mari had failed to make the “proper evidentiary showing” establishing the need for closure.

“I believe that the truth, in the long term, will lead to a better life for my children, for myself and for society in general,” Brinkley testified.
