The Feud actress, 48, took to Instagram on Saturday to post a throwback photo from her wedding to the 73-year-old actor in honor of the couple’s anniversary.
The duo were all smiles walking down the aisle after saying “I do” at New York’s Plaza Hotel back in 2000.
“17 years ago today, I said ‘I do’ to my best friend and father of our two and a half month old son,” she captioned the image. “Thought it could never get better than that day, but it did.”
Zeta-Jones continued, “Happy anniversary darling, Michael. With you, in my life, and Dylan and Carys, every day could be a twelve hour fantastic party at the Plaza in New York. Love you.”
Although they briefly split in 2013, Zeta-Jones and Douglas appear to be stronger than ever.
In March, they celebrated the 16th anniversary of their engagement by returning to the scenic Aspen, Colorado, location where Douglas proposed.
“I think love, without getting too corny, nourishing each other, working at relationships, good sustenance, good food, good kids, all kind of a combination,” he said at an AARP Movie Awards earlier this year.

The couple hit the Actors Fund’s Career Transition for Dancers Jubilee Gala in New York City together earlier this month. They held hands as they posed for photos and made their way down the red carpet.
The Cocaine Godmother star has also been posting photos of the estate she shares with her husband, 17-year-old son Dylan, and 14-year-old daughter Carys on Instagram ahead of her new home line with QVC.
“I prefer to have my life presented as it is by me. So many years in the public eye, somebody else decides who they think you are and how you live and what you do and what your taste is,” she said. “I love it because it really gives people the sense of getting to know me without any preconceptions.”
