Model Christie Brinkley told the court today that having a big happy family was the most important thing to her. However, for Brinkley, her plans were foiled by a husband who she claims, had an expensive Internet porn addiction and cheated on her with his barely legal personal assistant, Diana Bianchi.

She tearfully told the court: "That's the most important thing -- to have a big, happy family."

She also relayed how she had to tell her children: "I think daddy has fallen out of love with me." But she assured them they would always be "very, very loved."

Today however a new woman, Bridget Nisivoccia, has entered the mix. Although Nisivoccia, a 36-year-old interior designer, claims that her relationship with Cook was professional, Brinkley's lawyer is maintaining that Cook's affair with Bianchi "is just the tip of the iceberg."

Nisivoccia has not yet been named as a mistress of Cook's, though her name will come up in the trial later this week.

Brinkley and Cook were married for ten years. They have two children together.
