"Both Michael and I have a very open relationship," she said. "When you have kids that didn't ask to be born into a world where it's scrutinized or looked into. You've got to be open and honest and share things that probably people at the drugstore wouldn't share over the counter."
Back in January, Douglas revealed that he had been contacted by The Hollywood Reporter over a former employee accusing him of sexual misconduct. The "Ant-Man" star has denied all allegations.
When host Hoda Kotb asked if Zeta-Jones thinks that Douglas receives "too much scrutiny," the actress laughed and replied, "No, not at all. Michael's doing just fine."
The "Ocean's Twelve" star also explained how she and Douglas keep an "open" relationship with their kids, Dylan, 18 and Carys, 15.
"We share everything around the table," Zeta-Jones said. "I'm a big, European, kind of family girl and so everything is shared around the table: issues with my daughter if she's feeling insecure – she's a teenager and girls can be mean — and my son just going off to college, what that is for him, what it is for me because I never let on how I much I miss him terribly because he's having such a great time. So all of these conversations get around the table and so then I think you clear the air and everyone knows what's going on, there's no surprises."
Over the weekend, Zeta-Jones opened up to The Times about the "big conversation" she had with her children to break the news about their father's alleged sexual misconduct.
"My children and I were profoundly devastated by those allegations. And I was torn about where my absolute morals lie," she said. "This woman came out of nowhere and accused my husband. I had a very big conversation with him, with the kids in the room, and said, 'Do you understand if more comes out...'"
The Oscar winner called the situation "nasty" and said it put her in a "really hard position." Zeta-Jones added that Douglas told her "there is no story here" and "time will tell."
"There was nothing to back it up at all," she explained. "For any accusation that comes out that isn't backed up, that knocks the movement back 20 years."
Zeta-Jones also talked on "TODAY" about weathering the storms of marriage over the nearly two decades she's been with Douglas.
"It's been great," she said. "But I think it's just unfathomable to me that you would be with one person for 18 years and things are not rosy every day. They're just not."
"My mother and father are married for 52 years," she continued. "And they're a wonderful blueprint for me because I've seen the good, the bad and the ugly with them and they're still going strong."
