The former couple divorced after Brinkley learned of Cook's affair with his then-19-year-old assistant Diana Bianchi. Shortly after his cheating scandal broke, Cook then married Suzanne Shaw. The pair split in 2014. After Bianchi came forward in 2007, Cook was also accused of having romantic relations with another former employee, Samantha Cole, who was 18 at the time. He allegedly proposed marriage to her in May 1996 — three months before he became engaged to Brinkley — but she declined.
