Through the years, Catherine Zeta-Jones and Michael Douglas's relationship has continued to thrive, evolving into one of the most enduring partnerships in Hollywood since they met in 1998 and tied the knot in 2000 at the Plaza Hotel in NYC.
When asked in a 2021 interview with WSJ Magazine about the secret behind their 20-year-strong marriage, the Welsh actress explained their relationship had lasted because they still have lots of fun together.
She shared that "constant love and respect" and maintaining a "sense of humor" are key to marital success. Announcing in 2013 that they were taking a break from being together, they released a statement saying they wanted some time to "evaluate and work on their marriage".
Speaking to Event magazine in 2015, Michael admitted: "We had a little bump in the road. The problem in this business is that everything is so public. I love Catherine as much, more than I ever have. And hopefully the feeling’s mutual. We worked things out – if both people want to work something out and make it better, you can do it. You can’t do it if it's just one person."
Catherine also commented on the couple's 25-year age difference, explaining: "We're just very good with one another, we respect each other, and I never really feel that he's 25 years older than me. I remember people saying, 'When you're 50, he's going to be 75.' Well, that’s just maths."
