The other woman – a barely legal doe-eyed beauty – at the center of the sensational Christie Brinkley divorce trial in Long Island admitted she freely hopped in the sack with the supermodel’s much older hubby.
“In his office he asked me how I would feel if he told me that he was attracted to me and that’s really how it all started,” Diana Bianchi said under oath at Central Islip Supreme Court.
For nearly a year starting in the spring of 2005, Bianchi, then 18, carried on a torrid love affair with Brinkley’s dashing husband Peter Cook, now 49.
The pervy penchants of hubby Cook were topic No.1 at Central Islip Supreme Court as supermodel Brinkley’s attorney attempted to portray the man as a sex fiend whose virtual voyeurism and very real affair with an 18-year-old girl make him an unfit father.
Little seduction on Cook’s part was needed to get Bianchi in the sack.
“I think I was a little taken aback, but I wasn’t against it either really,” she said, dressed in white blouse and charcoal gray skirt that hung below the knee while wearing a rosary on her wrist.
“I wouldn’t say that one of us pushed the other. I would say that it was a mutual thing,” a nervous and sometimes stammering Bianchi said.
Earlier the shamefaced soon-to-be ex-husband of Brinkley burst into tears in as he recounted under oath how he spent his evenings ogling online porn while masturbating in front of strangers over a Web cam.
Perhaps the lowest point came when Cook admitted that his adopted son saw his cache of nudie pics on the computer.
Throughout the day of testimony, Cook, an architect, matter-of-factly answered questions about his hanky panky with the Diana Bianchi, a beautiful teenager, that he hired just for the chance to bed her.
But, when grilled over his online pornography passion the dapperly-dressed Cook lost control in the courtroom that was packed with media from around the world.
“Is it correct, sir, that you have masturbated in front of a Web cam,” his own attorney Mark Winkler asked.
To which a red-faced Cook – cool as a cucumber up to then – replied, “Yes, I have, privately, secretly, never at home, never in front of my children.”
Crying and wiping tears from his eyes, Cook admitted that he sough “young fit girls” from the online swinger Web site adultfriendfinder.com while confirming that he was a voracious viewer of hardcore pornography.
Jack, Brinkley’s now 13-year-old son from her previous marriage to Ricky Taubman, even caught a glimpse of his porn in 2006, Cook admitted.
“He said, ‘Mom is looking at naked pictures of your girlfriends on the computer,” Cook said as he cried.
Brinkely – who has been criticized by observers for opting for a public trial – also joined in the online orgies, according to Cook.
Cook testified that the two viewed pornography together.
“It was a precursor to sex,” Cook said before Judge Mark Cohen order that her porn passion be stricken from the records.
Under a blistering – and utterly humiliating cross exam – by Brinkley’s pitbull attorney Robert Cohen, Cook said his ten-year marriage to the supermodel was ruined by his torrid affair with an 18-year-old stunner, Diania Bianchi.
He confessed that he had eyes for the hottie since day one and only hired her a $20,000 a year clerk at his architecture firm in the hopes of teaching more than how to use a T-square.
“It was an inducement into hiring her,” he said.
Cook then coldly told Cohen that he slept with Bianchi 12 times – twice at his office and five times each at his homes in Sag Harbor and Water Mill – starting in March 2005.
He further admitted that in addition to paying her $20,000 for her clerical duties at the office he showered her with gifts like a $2,000 watch from London Jewelers and Victoria’s Secret lingerie and envelopes full of cash that he would hide around the office for her to find.
“I don’t know, you put me under your spell. You never asked me, but I left you money anyway,” Cook said as he read from a printout of one his love struck e-mails to the teen.
The public divorce trial between Brinkley, 54, and her architect hubby Cook, 49, is expected to last a month and will see a parade of more than 60 witnesses as the once inseparable spouses bitterly battled over custody of their two children, Jack, 13, and Sailor, 10.
Cohen painted a picture of Cook this morning as a lying lothario who absolutely devastated his wife after she learned off his torrid affair with then 18-year old Bianchi and later of his lascivious online habits.
But, Cook’s other lawyer Sheresky shot back that such a public airing of the couple’s sordid secrets do nothing but hurt their kids and proves Brinkley isn’t the supermom she pretends to be.
“Opening the case to the public is bad for the kids. That’s not good motherhood, that’s not acceptable,” Sheresky said. “She wants nothing but to get even. She and her lawyers and her PR people are pitching a new history.”
Sheresky owned up to the affair but said that doesn’t mean he shouldn’t see Sailor, whose birthday is today, and Jack.
“He did it and it was wrong. And we said so. And there is no way to make this right,” Sheresky said. “Peter has apologized. He’s cried his eyes out. He’s lost his marriage.”
He then pointed out that Brinkley herself has a poor marital track record whose insistence on a public trial is embarrassing the family.
“For goodness sake: She’s on her fourth husband,” Sheresky told the court. “Your honor, we’re here because of the self-indulgent wrath of a woman scorned. … That’s putting her agenda in front of the best interests of the children. What kind of a mother wants her husband flogged in public?”
Brinkley, dressed in a white shirt and a khaki skirt, appeared anxious and at times on the verge of tears but remain composed.
“To Christie, her union with Mr. Cook was near perfect,” Cohen said in the courtroom packed with media from around the world.
“She is blessed in that she had the flexibility and good fortune to continue her career as a model spokesperson and humanitarian.”
But, that world came to a crashing end in June of 2006 when Brinkley was giving the commencement address during the graduation exercises at Southampton High School.
Southampton Police Officer Brian Platt, Bianchi’s stepfather, approached her with news that shattered the 10-year marriage.
“I just wanted to tell you that that husband of yours is having an affair with my step-daughter,” according to Cohen’s recounting of Platt’s whispering to Brinkley.
“She was sick to her stomach. Every bone in her body ached, her world has been blown up,” Cohen said.
That day a distraught Brinkley – who at one point found herself hysterical on her knees in tears on the side of a busy road – confronted Cook.
The cheating hubby said it was Bianchi who seduced him, saying they only kissed until one day she just took off her clothes in his office and declared, “Let’s have sex.”
Brinkley then looked at Cook’s online habits.
“There was entire world of cybersex that Mr. Cook was involved in,” Cohen said.
He claimed that Cook spent $3,000 on Web pornography and membership fees to hot-sheet online dating sites like adultfriendfinder.com and hornymatches.com.
He pleasured himself over a Web cam, Cohen said, and would hit on potential sexual partners with lines like, “Hey there, I’m a horny dude, spare me the philosophy and ‘eff’ me,” Cohen said.
The architect also owned up to subscribing to iFriends, a site that allows viewers to instruct woman to strip off their clothes and cavort via a Web cam.
Cohen even brought up Cook’s 1982 cocaine bust for selling $125 worth of powder to an undercover cop in Huntington. Cook, 23, at the time ended up serving 60 days in jail.
Cohen further accused Cook of being a poor father who insisted the kids eat separately in the kitchen from the parents.
He also said Cook lost interest in his adopted son Jack after his biological daughter Sailor was born. He further became extremely critical of Alexa Ray Joel, 22, Brinkley daughter with her ex-husband Billy Joel.
Cook lunched on turkey with rice soup and crackers at the courthouse cafeteria while Brinkley was hustled into a private lawyer’s lounge away from the horde of media following their break-up.
“Hair and make-up,” Cook quipped to The Post about her need for privacy.
“What do I need privacy for?”
Meanwhile, a teary and clearly distraught Binachi shuttled between a restroom and private waiting area surrounded by court officers, as she waited her turn to testify.
At one point, Bianchi shared the bathroom with Alexa. It’s uncler if the two had words. They later stood side by side in an awkward silence as they waited their turns to take the stand.
Veteran divorce attorney Dominic Barbara, who sat in the proceedings and provided commentary for the numerous reporters on site, blamed Brinkley for creating the spectacle.
“I think she’s at fault for letting this go forward,” he said. “This is revenge and who is getting hurt? The children are getting hurt … I would have to an appellate court to stop an open trial.”
