Christie Brinkley's ex files lawsuit NEW YORK, March 3 (UPI) -- Christie Brinkley has been called a "narcissistic egomaniac" in court documents filed in New York by her ex-husband who is suing for money he says she owes him. Peter Cook, Brinkley's fourth husband, said Brinkley owes him $25,000 for looking after their two children while she worked on the musical "Chicago" in London and New York, The Daily Telegraph reported Saturday. After the couple's 2008 divorce, Brinkley was awarded custody of their daughter Sailor, 13, and Jack, 16, Brinkley's son by her third marriage, who Cook adopted. Cook's 91-page court document filed at Suffolk County Supreme Court in New York called the model a "narcissistic egomaniac" and said she would drag their children into the former couple's fights. He accused her of sending an e-mail to their son saying Cook was "jealous of my success." Brinkley, though, said Cook owes her $32,000 for school tuition and summer camp fees for the children.
