Zeta-Jones celebrated the occasion (she turned 47 and he turned 72) on Instagram Sunday with a sweet message to her longtime love and a photo of her kissing her smiling husband on the cheek.
"A birthday kiss for my hubby. Happy Birthday to you and me," the Oscar winner captioned the cute pic—a regram from their recent vacation in Saint Tropez—along with a kissy face emoji.
Despite their fair share of rough patches, the Hollywood power couple is still going strong and are quickly approaching their 16-year wedding anniversary.
"It's a long road and I think people today are so quick to throw in the towel on marriage," Zeta-Jones recently told Good Housekeeping. "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."
Happy birthday to the couple!
