Catherine Zeta-Jones is looking forward to many more years with Michael Douglas.

The 'Chicago' star shared an adorable black-and-white photograph of the 71-year-old actor kissing her on her forehead, with the caption: "Happy Anniversary dearest Michael! Loving our life together, here's to the next 15!"

The 'Ant-Man' actor also shared a recent photograph of them on his Facebook profile to mark the special occasion, writing: "15 years ago and today.... Happy Anniversary Catherine!"

The couple, who have daughter Carys, 12, and son Dylan, 15, together, briefly split in 2013 due to stress after the Welsh beauty was diagnosed with bipolar disorder and the 'Wall Street' star battled throat cancer, but continued to work on their relationship.

And earlier this year, Michael revealed their romance is firmly back on track, saying: "It can't be a one-way street. But I'm crazy about her. And yeah, I think every couple has their difficult times.

"The only problem is, as you well know, we're all in the public eye, and it tends to get a little more exposed than most. We're back stronger than ever."
