Happy birthday, you two!

Catherine Zeta-Jones marked her shared birthday with husband Michael Douglas on Sept. 25 with a sweet snapshot.

"A birthday kiss for my hubby. Happy Birthday to you and me. 😘," she captioned a pic of herself kissing her actor spouse.

The Welsh actress turned 47 while the "Wall Street" star turned 72.

In November, they'll celebrate 16 years of marriage.

Last year, she marked their milestone 15th wedding anniversary with another loving social media post.

"Happy Anniversary dearest Michael! Loving our life together, here's to the next 15! ❤️," she captioned a black-and-white photo of Michael kissing her.

The actors, who share kids Dylan, 16, and Carys, 13, reconciled nearly three years ago after separating in early 2013. Their temporary breakup followed some difficult years during which Michael battled stage four throat cancer and Catherine struggled with bipolar II disorder.

"It's a long road and I think people today are so quick to throw in the towel on marriage," Catherine told Good Housekeeping in March. "You have to give it your best shot and not give up when the first problem arises, because that won't be the last problem. There will be many more down the road."

In January, Michael told AARP The Magazine that he and Catherine had come a long way.

"It took work on both our parts," he said of their reconciliation. "I don't think there's much chance of fixing a relationship if one of you is already out the door."

The birthday photo Catherine shared this year is from a series of snapshots she and Michael took while vacationing in St. Tropez in July.

"Lunch in Saint Tropez. Happy all around!" she captioned a pic back then of herself and her husband beaming for the camera.
