Speaking to Hoda Kotb and Savannah Guthrie on NBC’s TODAY, the 49-year-old mum revealed that things aren’t ‘rosy’ every single day, but that she and Michael are always very open with each other and their two kids Dylan, 18, and Carys, 15.

“Both Michael and I have a very open relationship. When you have kids that didn’t ask to be born into a world where [the marriage is] scrutinised or looked into…”

“You’ve got to be open and honest and share things that probably people at the drug store wouldn’t share over the counter,” Catherine said.

Being open and honest about the realities of marriage, she said that there are hard times in any long term relationship.

“First of all, I’m so happy that we’ve made it to be 20 years together. It’s been great. 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. You know? They’re just not.”

For Catherine, family is all about talking things through and ‘clearing the air’ so there are ‘no surprises.

“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. My son’s going off to college. And then you just clear the air. Everyone knows what’s going on. There are no surprises.”

Catherine previously said that this was the approach she took after a ‘devastating’ sexual misconduct allegation came out against her husband – and she made sure to have a very big conversation with him about it while the kids were in the room.

Michael strongly denied the accusations at the time.

The ‘Ocean’s Twelve’ star’s parents – Patricia and David – have been married for over five decades and Catherine believes it’s been good to have them as inspiration to look up to.

“My mother and father are married for 52 years 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,” she told The Today Show.
