Former supermodel Christie Brinkley is putting a brave face on her estranged husband's marital infidelities - by buying a new home next to his 'love shack'. The 53-year-old catwalk beauty is in negotiations to buy an 18th century property in Long Island, New York, for $11 million (GBP5.5 million), despite its close proximity to the residence Peter Cook reportedly seduced his teenage lover Diana Bianchi in, according to the New York Daily News. Brinkley's publicist, Kathleen Lynn, insists the 'love shack' belongs to her, and was not bought with Cook in 2003: "It is hers and has always been hers." Brinkley filed for divorce from Cook in September 2006, two months after reports surfaced about his alleged affair with the 18-year-old assistant.
