The couple posted sweet tributes to each other on their Instagram accounts Saturday, to mark the milestone.
Alongside a carousel of photos of the couple from over the years, “The Mask of Zorro” actress, 54, wrote, “Today we celebrate 23 years of marriage❤️.”
“Darling Michael, your Nobel Peace Prize awaits😂😘❤️,” she continued. “I love you…from your darling wife, a gold star Medal of Honor recipient😘.”
To honor his wife, Douglas, 79, also shared a throwback photo of them dancing together at their wedding.
“Happy 23 and Me, my darling @catherinezetajones!” he captioned the post. “Can’t wait for 24! Happy Anniversary ❤️ #23years.”
Responding in the comment section, Zeta-Jones wrote, “Love you sweetheart, may our dance never end❤️.”
The pair, who share the same birthday, Sept. 25, tied the knot Nov. 18, 2000. They have two children together, Dylan, 23 and Carys, 20. Douglas is also a father to son Cameron, 44, whom he shares with ex-wife Diandra Luker.
During an interview with the Wall Street Journal in 2021, Zeta-Jones revealed the secret behind her long-lasting marriage, explaining that the No.1 ingredient to any marriage is laughter.
“We have a lot of fun together,” the actress shared at the time. “We’ve never, ever lost our sense of humor, and we enjoy each other’s company.”
Zeta-Jones also added that what truly fuels their relationship is the fact that “we respect each other’s space, and our humor is just long-lasting.”
