Christie Brinkley’s ex-husband, Peter Cook, is reportedly engaged.

Cook, 60, is said to have proposed with a six-carat diamond ring during a trip to Santorini, Greece, in September, Page Six reports.

“We consider ourselves incredibly lucky to have found, in each other, our soulmate. We are looking forward to many years of wedded bliss!” the groom-to-be told the outlet, who also reported that the couple plan to tie the knot in Europe.

Cook, an architect, married Brinkley in 1996, but they went their separate ways in 2008, after Brinkley accused Cook of cheating on him with an 18-year-old.
