Lawyers for Christie Brinkley and Peter Cook traded barbs after another acrimonious day
of testimony Thursday.
Norman Sheresky, Cook's lead attorney, repeated his assertion that the supermodel pushed for the trial
to punish her architect husband.
"I think it's pretty clear she's doing this out of revenge," he told reporters.
Later he said, "during the custody case you're going to find out how angry she was. There's an independent doctor who was appointed in this case. He said she was boinkered by anger."
Brinkley's lawyer countered to PEOPLE, "I still don't understand why we have to go through this. I guess this is what (Cook) wants."
The custody phase of the trial begins Monday. Both sides are seeking sole custody of Jack, 13, and Sailor, 10.
Sheresky said Cook is seeking sole custody because Brinkley has inappropriately criticized Peter in front of the kids.
"She was a wonderful mother for a long time," he said. Asked about now, he replied, "No, she's not. She wants to slam Peter every time she can."
Sheresky also praised Cook as "an able father" who will "promote a good relationship" with Brinkley.
