For years, Peter Halsey Cook name has appeared in stories about supermodel Christie Brinkley. Yet the familiar description of him as her former husband omits an important part of his life: he built a career designing homes in the Hamptons before their marriage drew national attention. His story links private residential design with the visibility of a celebrity family.
Cook is an American architect whose public profile grew during his marriage to Brinkley, which lasted from 1996 to 2008. He is also the father of model Sailor Brinkley-Cook and the adoptive father of Jack Brinkley-Cook. He married Alba Jancou in 2023.

His Background and Connection to the Hamptons
Cook’s professional identity is closely tied to Long Island’s East End. Beyond its famous residents, the area has a distinctive architectural tradition. Shingled exteriors and generous porches are familiar elements of its homes.
Public accounts place Cook’s upbringing in New Jersey and his later professional development in the Hamptons. Detailed, independently documented information about his childhood and education is comparatively limited. His architectural work offers a clearer starting point than unsupported childhood details.
Building a Career in Residential Architecture
Long before his personal life became tabloid fodder, Cook was designing custom homes. Reports of his early career describe an apprenticeship with Hamptons architect Eugene Futterman, followed by the establishment of his own practice in 1987. He was therefore established in the field before he married in 1996.
His work is associated with traditional Hamptons residential design, especially shingle-style houses. A notable example was his renovation of the historic Bridgehampton property he shared with Brinkley. The restoration retained the character of an older home while introducing spaces better suited to contemporary family living. It illustrates a familiar challenge in the Hamptons: preserving architectural character while making an older property comfortable for modern life.
Cook updated another Bridgehampton home, dating to 1850, and it later appeared in national design coverage. These projects offer a clearer view of his working interests than the headlines about his marriage.
His career should not be confused with that of Sir Peter Cook, the British architect associated with Archigram and experimental architecture. Despite the shared name and profession, the two men have separate careers and histories. Keeping that distinction clear also prevents people from wrongly crediting unrelated buildings, awards, or academic appointments to the American architect.
Marriage to Christie Brinkley
Cook and Christie Brinkley married in September 1996. Brinkley was already one of America’s most recognizable models, with a career spanning magazine covers, advertising campaigns, and television appearances. Their relationship brought Cook attention beyond his architectural clients.
The couple raised a family in the Hamptons, a place connected to both their professional and personal lives. They welcomed their daughter, Sailor, in 1998. That family chapter lasted more than a decade.
Their Separation and Divorce
The marriage came under intense public scrutiny when the couple separated in 2006. Their divorce was finalized in 2008 after widely reported legal proceedings. The proceedings brought difficult personal matters, including an acknowledged affair and family disputes, into public view.
In her 2025 memoir, Uptown Girl, Brinkley looked back on the painful period and described the separation from her perspective. The book renewed attention to a marriage that had ended years earlier. It is an important part of the public record, but it does not reveal everything about Cook’s life since the divorce.
Children and Family Relationships
Brief celebrity profiles sometimes present family connections inaccurately. Cook and Brinkley share one biological child, Sailor Brinkley-Cook, who has built her own modeling career. Cook also legally adopted Jack Paris Brinkley-Cook, Brinkley’s son from her earlier marriage to Richard Taubman.
Brinkley has another daughter, Alexa Ray Joel, with musician Billy Joel. Alexa is part of Brinkley’s wider family, but she is not Cook’s biological daughter. These distinctions clarify the family’s public history without assuming details about private relationships.
Suzanne Shaw and His Marriage to Alba Jancou
After divorcing Brinkley, Cook married Suzanne Shaw. That marriage also ended, although it received far less attention than his first. He became engaged to Alba Jancou in 2019.
Cook and Jancou married in September 2023 on Capri, an Italian island. Their ceremony at Hotel Luna was a small gathering overlooking the island’s distinctive coastal scenery. They had initially considered a wedding in 2020, but the pandemic disrupted those plans. The wedding marked another documented chapter in his life.
Age, Finances and Life Today
Biographical listings commonly list Cook’s birth year as 1959, which would make him 67 in 2026. However, independent reporting does not document details such as his exact birth date, education, and height. Uncorroborated details merit caution.
The same caution applies to his net worth. Cook has worked in a field associated with expensive properties, but the price of a house he designed or renovated does not prove his personal fortune. No independently verified public accounting establishes his current net worth, so a precise dollar figure would create more certainty than the available facts justify.
Cook has continued to appear occasionally at public events. In August 2025, he was photographed at the Hampton Classic Horse Show with Alba Jancou and Sailor Brinkley-Cook. The appearance documents a public moment, not his current residence or daily activities.
Conclusion
Peter Halsey Cook’s public story is often told through his connection to Christie Brinkley, yet his architectural background gives it a wider context. He built a career in the Hamptons, joined a well-known family, and underwent personal changes that were sometimes discussed far beyond his professional circle.
The most useful picture is neither a polished celebrity profile nor a replay of old headlines. It is a measured account of an architect whose work, family ties, and documented later marriage explain why his name still attracts interest, while leaving the undocumented parts of his life where they belong: private.
