The couple with the most contentious divorce in Hollywood has finally found one thing to agree on -- they will never, ever exchange words again. Not so much as a peep, according to Radaronline.com. Blonde bombshell Christie Brinkley and ex-husband Peter Cook finally came to an agreement after six years of haggling over child custody and other issues. Ironically, son Jack is 17 and one year away from being an adult, while daughter Sailor is already 14. Had they not come to a consensus, the fiery fight would have continued on in the courts. Cook and Brinkley had a bitter split six years ago after the 58-year-old uptown girl discovered her spouse was having an affair with an 18-year-old girl. Since then, their feud has played out in public forums as they constantly attacked each other. Although it's highly unlikely the barbs will cease, two things are for certain -- they will abide by a "verbal contact" order and they will communicate through a parent coordinator, who will act as a liaison between the two. Despite the agreement, it was business as usual between Brinkley and Cook. His lawyer issued the following statement, "Mr. Cook has also secured a parenting coordinator, something he has sought, and Ms. Brinkley has refused, for 4 years." Meanwhile, Brinkley took to her Facebook to express her feelings, "It has been an odyssey of frustration as I have navigated the court system with one goal to find peace and protection for my family from the various forms of abuse at the hands of a narcissist."
