CHRISTY BRINKLEY DUMPS DIRTY HUSBAND

Christie Brinkley has filed for divorce from Peter Cook two months after reports surfaced about his alleged affair with an 18-year-old employee, Cook's lawyer confirmed Thursday. "We are told that a divorce action has been commenced in Suffolk County, and we have agreed to accept service of those papers," lawyer David Aronson told The Associated Press. The divorce papers were filed in Suffolk County Court in Riverhead. "I can neither confirm nor deny it," Brinkley's publicist, Elliot Mintz, reached in Los Angeles on Thursday morning, told the AP. The 52-year-old supermodel announced in July that she and Cook, 47, her fourth husband, had separated. They were married in 1996, and have an 8-year-old daughter, Sailor. Cook adopted Brinkley's son, Jack, now 11, from her marriage to developer Richard Taubman. Aronson said Cook "regrets that this happened. He was hopeful that he and Ms. Brinkley would be able to work their way through this problem and put their marriage back together, but obviously she has decided otherwise."
