UPDATE! 5:30pm – As court adjourned for the day, Christie Brinkley spoke for the first time. She told reporters that during today’s testimony, she “heard a lot of new things I didn’t know.” As she heads home, Dvorkin and I will stick around for hits at 7pmET and possibly 10pmET. Tune in for fresh video and soundbites from the key players.

UPDATE! 4:45pm - The “other woman,” Diana Bianchi, is on the stand now. She has admitted having an affair with Christie Brinkley’s husband, Peter Cook. Earlier, Cook admitted the affair began when he was 46 and Bianchi was “18-and-a-half”.

My producer and I have been updating viewers on FOX News Channel nearly every hour today. Now we’ll go do live shots for various local FOX stations around the country. Busy day for us – but no complaints. I’d rather be working than testifying in a divorce battle, any day.

8:50am - Brinkley just arrived at court, flocked by news crews and paparazzi. Cook entered the courthouse moments later. When asked if he’d ever get married again, he said “I never thought I’d get divorced.”. Two paparazzi photographers literally got into a fight when one said the other blocked his shot of Brinkley and damaged his camera.

Christie Brinkley’s divorce/custody battle against Peter Cook kicks off today in a Long Island courtroom. The former couple reportedly had a prenup, but despite they they still have boats, some real estate, and most importantly, 2 children to fight over.

FOX Entertainment-Producer-Extraordinaire Ashley Dvorkin and I met up at the FOX News headquarters at 6am to head to Long Island.

Leading up to today, we’ve talked to both sides. Peter Cook wanted this case closed to the public. However, the judge ruled to keep it open to media. Cook’s lawyer, Norman Sheresky, blamed Brinkley, telling me, it’s a “terrible, terrible, almost inexcusable thing to do, for a parent to want press present at a custody or divorce hearing. It’s outrageous.”

Meantime, Brinkley’s lawyer, Robert Cohen, tells FOX News, “”The only way the truth is going to come out is through a public trial. Mr. Cook should not have done anything that he would be embarrassed about.”

Today outside the courthouse, the scene is packed with news crews, satellite trucks and reporters from TV, radio and print. Cameras are not allowed inside the courtroom, so our cameraman will stay outside, another FOX producer will be taking notes inside, and I will be running back and forth between the courtroom and our liveshot location.

Many reporters are waiting to hear from the “other woman” in this case, Diana Bianchi, whose relationship with Cook began when she was 18 years old. When the story of their affair first broke in 2006, Bianchi’s lawyer told FOX affiliate WNYW that Cook “preyed on [Bianchi’s] age and vulnerability.”

Tune in to FOX News all day today for the latest scoop from the courthouse, as Brinkley and Cook battle for custody and property.
