The 35-year-old actress revealed that she is determined to handle the split in an adult way for the sake of their son Joe, seven, and her daughter Mia, from her first marriage to husband Jim Threapleton.
“One thing I will say about me and Sam is that it's fine, it's really fine,” she told Harper’s Bazaar.
“We’re grown-ups at the end of the day, and however hard it’s been for me, it’s been equally hard for him.”
“There’s no way that I’m going to allow my children to be f***ed up because my marriages haven’t worked out.
“I so wish that that wasn’t the case, that that hadn’t happened in my life, but it has. So I will make the best of it.”
Now believed to have moved on with Richard Branson’s nephew Ned Rocknroll, Kate admitted that she had a hard time allowing her emotions to show in the weeks after the split.
“As a woman, especially when you have children, one gets so good at soldiering on – almost too good. Because you know what it's like – as soon as you open that can of worms, it’s so f***ing big, you wish you’d never taken the goddamn lid off.
“I’ve had to remind myself to have those moments of being able to have a f***ing good cry, but it did take someone putting their hand on me – a gay male friend, actually, who put his hand on my shoulder and said, ‘It's OK, you can cry about this, and maybe you should’.”
