LATEST: The second day of Christie Brinkley and architect Peter Cook's divorce trial has been another emotional one with high drama as the model took the witness stand on Thursday (03Jul08).
After Cook broke down during a cross-examination by his lawyer in Long Island, New York on Wednesday (02Jul08), it was Brinkley's turn to fight tears on the stand.
The 54 year old told the court about the day she discovered her husband was cheating on her with a teenage assistant.
Brinkley recalled then-18 year old Diana Bianchi's stepfather telling her the shocking news after she had delivered a high school commencement speech in June, 2006.
The model, who was once wed to rocker Billy Joel, admitted she knew immediately her husband was guilty.
Fighting back tears in court she said, "I thought, 'Oh my God, it's true. He did it...' It explained the feelings I was trying not to feel."
Brinkley recalled leaving Cook later that same day, admitting, "I drove away from my perfect life... I thought we were happy."
The model also revealed more about Cook's Internet porn passion, which had been discussed in court the previous day.
She revealed, "I found conversations of him trying to lure girls saying he would take them shopping, saying he would pay them if he could see their face.
"I felt really stupid... I felt humiliated. I felt shattered. I just felt grief-stricken."
But Cook was far from impressed with his estranged wife's emotional testimony, telling reporters during a break in proceedings, "Shrek was more believable than that."
