The 45-year-old star couldn't help but gush about her husband when she attended a charity gala with him on Monday evening.
"If he wasn't my husband, I'd like to work with Michael Douglas," Catherine told reporters. "It's true, he's a great actor."
Michael, 70, was just as complimentary about his wife and told her: "I would like to work with you any way I can get you, honey."
He added: "It’s a good question, I’ve been wondering myself, you’re not playing hard to get now, it’s too late."
The Basic Instinct star went on to say that he "really lucked out" when he met his stunning wife, and also boasted about how he spoilt her on US Mother's Day last Sunday.
Revealing that he showered the mother-of-two with "flowers and gifts and lots of love and affection", Catherine added: "I had probably the best Mother's Day.
"One of the best days I've had in many, many years. We were all together. I got spoiled rotten."
The happy couple, who have been married for 15 years, appear to be firmly back on track after a brief separation two years ago.
The turbulent time saw Michael diagnosed with throat cancer as Catherine underwent treatment for bipolar disorder.
Despite the rough patch, they reunited towards the end of 2013.
Speaking at The Actors Fund for Everyone in Entertainment in New York City, the pair also emphasised the importance of spending time as a family with their two children, 14-year-old Dylan and 12-year-old Carys.

Speaking of summer plans, Michael said: “I've got to promote Antman until I’m another year older, until I’m 78 or something.
"Catherine’s got a fun picture she’s looking forward to doing. We try for as much as much as we can for the summer to be with the kids.”
"We like to be with the children," Catherine added.
