Supermodel Christie Brinkley experienced an uncomfortable reunion with ex-husband Peter Cook at a high-profile East Hampton fundraiser, where she was signing copies of her memoir that details their tumultuous marriage and Cook's affair with a teenager. Cook attended the event with his new wife, Alba Jancou, who is a year younger than the daughter he shares with Brinkley, adding to the awkwardness of the encounter. Brinkley recounted in her book how she learned of Cook's infidelity from a local police officer, leading to a painful divorce and custody battle. While Brinkley remains single and has joked about marriage renewal options, Cook has moved on, marrying Jancou in a romantic ceremony in Capri.
