The answer to this question depends on how you define "biggest" and "famous." However, some couples with notable age gaps include:
- Hugh Jackman and Deborra-Lee Furness: Jackman is 13 years younger than his wife. They have been married since 1996 and have two adopted children.
- Harrison Ford and Calista Flockhart: Ford is 22 years older than Flockhart. They married in 2010 after dating for eight years.
- Michael Douglas and Catherine Zeta-Jones: Douglas is 25 years older than Zeta-Jones. They married in 2000 and have two children.
- Priyanka Chopra and Nick Jonas: Jonas is 10 years younger than Chopra. They married in 2018 and have a daughter.
These are just a few examples of famous couples with significant age differences. There are many others, and the definition of "biggest" can be subjective.
