Former supermodel Christie Brinkley paid ex-husband Peter Cook $2.1 million in a divorce settlement in which she gained custody of their two children.

Brinkley filed for divorce in 2006 after she discovered that Cook, 49, had an affair with 18-year-old Diana Bianchi, an employee at his architecture firm, whom he paid $300,000 to keep their relations quiet. During the five-day trial, Cook admitted to a $3,000-per-month Internet pornography habit.

Brinkley, 54, was previously married to Jean-Francois Allaux, Billy Joel and Richard Taubman before her 10-year marriage to Cook.

The ex-model will keep 18 disputed properties in the Hamptons, and Cook will get supervised parenting time with Jack, 13, and Sailor, 10.
