Christie Brinkley's Shame: Ex Peter Cook, 60, Engaged To College Co-Ed Same Age As His Daughter, 21

Out with the old and in with the — young!

Christie Brinkley's ex husband Peter Cook is set to be married to a 21-year-old college co-ed after he popped the question to her last month.

Cook, 60, got engaged to Alba Jancou in Santorini, Greece on Sept. 15., Page Six was first to report.

“We consider ourselves incredibly lucky to have found, in each other, our soulmate. We are looking forward to many years of wedded bliss!” Cook commented about the engagement.

The couple were first linked together over the summer when they were spotted canoodling at several different Hamptons events.

Page Six exclusively reported over the summer that the pair were dating — after they’d been spotted together looking close at a series of Hamptons events, including chef Bobby Flay’s Hamptons magazine cover party, and two East Hampton charity events.

But a pal of the couple said: “They originally met two years ago at Le Bilboquet, but didn’t start dating until a year ago. They are planning a destination wedding in Europe.”

Cook proposed to Jancou with a whopping six-carat diamond ring by jewelry designer Glenn Bradford.

Jancou is expected to graduate from Tulane in 2021. According to her LinkedIn page, which has since been deleted, she also “attended a prestigious English private boarding school,” called Millfield.

Cook and Brinkley, 65, share one daughter together, Sailor, who is the same age as her famous father's new bride-to-be.
