During her two-hour testimony Thursday morning, Christie Brinkley aired more of Peter Cook s dirty laundry.

Brinkley detailed a call she received from Cook shortly after she discovered news of his shocking affair in 2006, describing her estranged husband as being hysterical and suicidal. “He was sobbing and said he was driving erratically and that, ‘I’m going to drive into a tree,'” Brinkley said on the stand. “I said, ‘Pull over. You need help.’ He said, ‘No, I’m going to kill myself.’ Then I spent the rest of the day trying to find a place he could go to get help.”

But the revelations didn’t stop there. On the heels of testimony Wednesday from her daughter Alexa (her dad is singer Billy Ray Joel) that Cook once punished her by shoving her head into a bucket of water, Brinkley said the strain between Cook and Alexa, 20, “was truly an area that pained me in our marriage.”

Under cross-examination, Cook denied shoving Alexa’s head into a bucket.

After the couple welcomed their daughter Sailor in 1998, Brinkley says Cook s relationship with Alexa changed. “He would constantly be picking on her. It got worse and worse over the years,” Brinkley said Thursday. “Finally one day I told Peter, ‘You married me and my two children. If you can’t love all of us, I can’t stay in this marriage.'”

Brinkley also testified that she insisted he see a therapist to work out his issues with Alexa. “He did, to his credit,” Brinkley said.
