The couple, who are set to celebrate 16 years of marriage this November, just rung in their birthday.
Catherine celebrated her 47th year, while hubby Michael turned 72.
To mark the occasion, Catherine shared a sweet snap on her Instagram.
“A birthday kiss for my hubby. Happy Birthday to you and me,” she captioned alongside a very sweet photo of herself giving her leading man a kiss on the cheek… Much to Michael’s amusement!
The couple tied the knot back in 2000, and are proud parents to 13-year-old daughter, Carys, and 16-year-old son, Dylan.
Unlike most Hollywood marriages, the pair have always been open and honest about their relationship.

The married duo briefly split in 2013.
At the time of the break, a family friend told People, “The stress has taken a toll on their marriage,” speaking of Michael’s 2010 cancer battle and Catherine’s struggles with bipolar II disorder.
“They want the best for their kids, no matter what happens.”
It all worked out, and the couple are stronger than ever!
“I think love, without getting too corny, nourishing each other, working at relationships, good sustenance, good food, good kids, all kind of a combination,” Michael mused at an AARP Movie Awards earlier this year.
While Catherine kept it real during a chat to Good Housekeeping.
“It’s a long road and I think people today are so quick to throw in the towel on marriage,” the Welsh actress admitted.
“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!”
