Harrison Ford and Calista Flockhart

The 'Indiana Jones' star 81, and the ‘Ally McBeal’ actress, 56, have 22 years between them but that didn’t stop them walking down the aisle in 2002 and Harrison adopting Calista’s 22-year-old Liam at the same time.

Harrison - who adopted Calista’s son Liam, now 22, after they wed - said in 2003: "I'm in love. Romantic love is one of the most exciting and fulfilling kinds of love and I think there is a potential for it at any stage of your life. I was not surprised that I was able to fall in love, and I wasn't surprised that I did."
