She says Peter Cook nude photos were posted on swingers websites while the shady Long Island architect went looking for young women.
He says Christie Brinkley was more concerned about going to public events than raising their two children, Jack, 13, and Sailor, 9.
Yes, the divorce trial between the estranged Christie Brinkley and Peter Cook officially kicked off today and it's already getting ugly.
Christie Brinkley's lawyers say Peter Cook loves him some online porn (spending $3,000 a month on it!), once masturbating in front of a web cam and regularly frequenting escort and swinger sites, all while married to Brinkley.
Brinkley also alleges, among many other things, that son Jack accidentally found naked pics of young girls on Cook's computer. The lawyers have also highlighted Peter Cook's felony cocaine conviction and the time he served in jail.
Cook and Brinkley split in 2006 after he had an affair with his assistant, Diana Bianchi, who was 18 at the time - and is scheduled to testify. He has admitted that he slept with her - and paid her $300,000 to keep quiet about it!
Also expected to testify: Carri Lyn Ciamarra, a fitness model who allegedly began dating Peter Cook right after his split with Brinkley.
In addition to battling for custody of the two children, the estranged spouses are also expected to wage a war over their jointly held properties and more than $3 million in material items, according to the New York Post. Stay tuned.
