Harrison Ford and Calista Flockhart
The next couple on our list has been together since 2002, tying the knot in 2010. They share one adopted son, Liam, and maintain a low profile, except when it comes to their work on the big screen.
Ford and Flockhart met at the 2002 Golden Globes and started dating. Despite their 22-year age gap, it hasn't affected their over two-decade-long relationship. Their combined net worth is $330 million.
