GRETA VAN SUSTEREN, FOX NEWS HOST: Tonight: Just when you thought it couldn't get any nastier, well, it has. Christie Brinkley and Peter Cook go back to court for day three of their divorce proceedings. Back on the stand today, Christie Brinkley.
Joining us live is Mona Rivera, reporter for 1010 WINS. Mona spent the day in the courtroom. Mona, Christie Brinkley was on the witness stand. What did she have to say?
MONA RIVERA, 1010 WINS: Well, it was a very different Christie today than last week. We had her last Thursday crying, sobbing. She was the broken woman, the woman who had been betrayed. Today we saw the ideal mom, the upbeat Christie, smiling, her face lighting up as she talked about her kids. A very different emotion in the court today, Greta.
VAN SUSTEREN: All right, Mona, they don't want to be married to each other. That's clear. So what is this dispute about? It's not just -- I mean, it's about their children mostly, isn't it?
RIVERA: It is. And today started the custody phase of the trial. Christie wants to say she's the better parent. Peter Cook wants to say he's the better parent. Both of them are fighting for full custody of these children, two children. One of them is the biological child of Christie and Peter Cook. The other one is Jack. He was adopted by Peter Cook when he was 4. And they are fighting over custody of these kids. That's the main focus of this trial.
VAN SUSTEREN: All right. So with Christie Brinkley on the witness stand fighting for custody, Peter Cook's lawyer -- did the lawyer have a chance to question her yet? And were there any sort of scored points, any weaknesses in why she should be the custodial parent?
RIVERA: Well, Greta, today he got about 40 minutes of cross-examination in after Christie had gone through a litany of descriptions about how she's the better parent. But he did get 40 minutes of cross-examination in. He scored a couple of points. He got Christie to admit that years ago in magazine interviews, she basically said that Peter Cook was the greatest father there was. And he said to her, "Did you mean that?" And she said, "Partially."
VAN SUSTEREN: All right. The -- I mean, we have the drama inside the courtroom and then outside, sort of the battle of smearing in the public domain. Who do you think is winning that? I mean, is Christie winning the PR battle or is Peter Cook?
RIVERA: Christie has a PR person who accompanied her to the courtroom last week. She speaks to the cameras every time she passes by at the end of the day. Peter Cook goes down the stairwell. He goes into the elevator. He basically is hiding from the media.
VAN SUSTEREN: How many women so far has he at least admitted to or at least pretty solid evidence of girlfriends during their marriage?
RIVERA: Well, you know, you know, he obviously admitted to the teenage lover, Diana Bianchi. He has not admitted to any other extramarital affairs. However, he is officially still married and he has a new girlfriend.
VAN SUSTEREN: Diana Bianchi -- there was some suggestion she got a big chunk of money. How much did she get or how much has Peter Cook admitted to giving her, and why?
RIVERA: Well, she has admitted on the stand of getting at least $300,000 in hush money. She also got $15,000 toward a car. She got a $2,000 watch. She got hundreds of dollars for other things like dental bills. Money was exchanged behind rocks, behind paintings, secretly passed to her during their affair.
VAN SUSTEREN: All right. Was this Peter Cook's money or is this Christie Brinkley's money that went to the girlfriend? And I should add, the $3,600-a-month bill for his pornography on the computer.
RIVERA: Yes, that's a very good question, Greta. No one actually really asks that. But Christie has said repeatedly on the stand, I supported this man for 10 years. Not only -- I mean, he would go out and buy clothing for the children and he would bill it to her.
VAN SUSTEREN: Any idea what he makes a year? He's an architect, right? Is he a successful one?
RIVERA: There has been absolutely no testimony about whether or not he has a salary.
VAN SUSTEREN: Is he asking for any alimony from her?
RIVERA: Well, that's the third phase of the trial, so we haven't heard yet what he's asking. But as you know, Greta, when whoever gets custody of the kids, the money follows the kids.
VAN SUSTEREN: That's right. There's going to be this issue of child support, and always, you know, they've got the child support and you've got the whole issue of alimony, too, at some point. Mona, thank you. Never dull.
RIVERA: Never a dull moment.
VAN SUSTEREN: Indeed, it isn't.
