Unlike someone looking for a sugar daddy/mommy, when celebrities get into relationships with older people, there is usually a different reason. It could be career moves; maybe it’s a midlife crisis, it can be compatibility and even love. The one thing they’re always mindful of is the age gap.

For that, there’s an equation that, while not scientifically proven, still does a good job. It’s called the half your age plus seven rule, where the older person in the equation halves their age and adds seven, if the younger person is the same age or older, good stuff. If not, be prepared to be called a cradle snatcher.

Michael Douglas & Catherine Zeta-Jones – 25 Years

At the start of their relationship, Michael Douglas and Catherine Zeta-Jones were one of the most talked-about celebrity relationships. The celebrity rags couldn’t get enough of their charm, and of course, taking stabs at the 25-year age gap between them.

Funnily enough, it was Zeta-Jones who was infatuated with Douglas when they met for the first time in France. It’s rumored that all he told her was that he wanted to father her children, and she was ready to walk down the aisle. He has fathered two children with her, and they got married in 2000. Douglas is currently filming Ant-Man and the Wasp: Quantumania.
