Christie Brinkley 's ex husband Peter Cook, 60, is engaged to his 21-year-old student girlfriend and is set to marry her.
Hamptons-based architect Peter announced his engagement to college student Alba Jancou on Tuesday.
The pair have been dating for a year, and he split with Christie, 65, in 2006 when he was caught having an affair with his 18-year-old office clerk Diana Bianchi.
Cook shares daughter Sailor, 21, with his ex wife, and also adopted her son Jack, 24.
He popped the question to his girlfriend - who is the same age as his daughter - last month on the Greek island of Santorini, reported by Page Six .
Peter called the 21-year-old his "soulmate" despite the 40-year-age gap between them.
"We consider ourselves incredibly lucky to have found, in each other, our soulmate," he told the publication.
He added: "We are looking forward to many years of wedded bliss!"
A source 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."
The bride-to-be is a psychology student in New York and Page Six were told she is Swiss, French and English.
In photos of the engagement, the couple is dressed in all white in front of the Santorini backdrop, admiring her ring created by jewellery designer Glenn Bradford.
He proposed with a 6-carat diamond ring in front of a church on September 15.
His second ex, Suzanne Shaw, who is in her 40s, accused him of having a "secret pathological predilection" for young women.
The pair divorced in 2014 after two years of marriage.
