Sacha Baron Cohen and Isla Fisher – 18 Years
We all know—at first glance, Sacha Baron Cohen and Isla Fisher appear to be an odd match… But after you see them together, you’ll realize why they’re paired. The pair met in Sydney, Australia, in 2002 and began dating immediately. They were engaged a year later and married six weeks later in Paris as Fisher converted to Judaism.

The wedding was quiet and small, as the bride explained since it was “extremely vital to me to have a lovely ceremony with my family and friends.” The pair now divides their time between Los Angeles and London, where they share custody of their two daughters and son.
