On the second day of testimony in supermodel Christie Brinkley's super screwed-up divorce case, Brinkley says almost ex-hubby Peter Cook once called her threatening to kill himself by smashing his car into a tree.
Brinkley said she begged Cook not to do it because it would destroy their children. When asked why -- Christie responded "it was the right thing to do."
And -- if you can believe it -- the story gets better.
Christie says Petey repeatedly denied the affair. She says she was "shocked" because her picket fence perfect life had been "shattered" and "vanished."
