The marriage has ended, the divorce has ended and Christie Brinkley says she feels no regret for the union with Peter Cook, as it gave her “Sailor, my beautiful little daughter” of whom she now has full custody, along with son Jack.

Christie Brinkley ad Peter Cook had engaged in a bitter divorce trial that looked as if it would drag on for a while but the two estranged spouses reached a surprise settlement Thursday morning, reports People.com.

Of the denouement, Brinkley told the media Thursday after the settlement became official in the Central Islip court that it was “a very bittersweet moment.”

Visibly pleased with the outcome, the 54-year-old former Sports Illustrated model commented that “it really is the death of a marriage, but it’s also I think a new start for all of us.” She added that she was “very pleased.”

What Christie Brinkley, Peter Cook ad their respective legal teams agreed on was for the mother to receive full custody of Sailor, 10, and Jack, 13, while the father was awarded “parenting time.”

Brinkley also keeps all 18 properties in the Hamptons and will pay $2.1 million to the 49-year-old architect.

A court-appointed psychiatrist testified in court Tuesday that the “only viable” option was for the two children to live with their mother, while the father remains involved in their lives.

Sailor is the couple’s daughter during their marriage. Jack is Brinkley’s son from her previous union with Richard Taubman, whom Cook adopted. Brinkley has a third child, 22-year-old daughter Alexa Ray Joel, from her marriage to singer Billy Joel.

At the onset of the divorce trial both parents were seeking full custody of the children. Dr. Stephen Herman of Manhattan, appointed by the court to analyze Christie Brinkley, Peter Cook and their two young children, essentially testified that the whole family needs therapy.

He characterized Cook as “a narcissist” who has “an insatiable appetite” to have his ego fed. He added that the architect “needs constant reassurance that he is a terrific guy.” Of Christie Brinkley, Herman said she needs therapy as “an outlet for her anger and feeling of betrayal” by her unfaithful husband and he questioned “her choice of male figures” and her repeated failed marriages.

The psychiatrist also said the two children would need counseling.

Christie Brinkley seemed ready to leave all the luridness of her unsuccessful marriage behind, telling reporters, “I’m really glad that today we found some peace.”

Peter Cook, who has been exposed as a cheating husband (and with a teenage assistant at that) and an Internet porn addict (expensive too, it was revealed in court, at $3,000-a-month), would only say while leaving court quickly, “I got everything I’ve been asking for two years.”

The couple’s ten-year marriage came to a shocking stop in 2006, when Peter Cook’s extramarital affair with his then 18-year-old assistant became a public scandal. The first part of the couple’s divorce trial focused on Cook’s wrongdoings: the affair, the expensive online porn habit, his attempt to buy his mistress’s silence.

Cook admitted all these accusations and apologized for them.
