Christie Brinkley’s lurid divorce trial came to an abrupt end Thursday when lawyers for the supermodel and her fourth husband reached an out-of-court settlement that gives her custody of their two children.

The settlement was reached at 6:15 a.m. after an all-night session that resolved all issues between Brinkley and her estranged husband, architect Peter Cook, Brinkley’s lawyer, Robert Stephan Cohen, told the court.

Under the agreement, Brinkley will give Cook $2.1 million but keep 18 properties in the Hamptons that were at dispute. Cook will get parenting time with the children, under an agreement mutually satisfactory to both.

Cohen said the remainder of the settlement was confidential.

Brinkley, 54, was married to Cook for a decade before his affair with a teenager he met in a Southampton toy store catapulted their troubles into the public spotlight in 2006.

The trial, which was in its sixth day, revealed a litany of salacious allegations about Cook’s affair with 18-year-old Diana Bianchi, as well as interactive Internet sex liaisons that cost him thousands of dollars a month. Cook, 49, testified he gave Bianchi a $300,000 payoff after having trysts with her in his office and Brinkley’s Hamptons homes for several months in 2005.
