The 'Supernova' actor has never stopped mourning for Kate, who died from breast cancer in 2009.

The father-of-five - who had twins Isabel and Nicolo, 21, and 19-year-old Camilla with the late social worker - admitted it will "always be hard" for the kids and himself, but they do their best not to "wallow" in grief, as that's not what Kate would have wanted.

Speaking on 'CBS Sunday Morning', Stanley said: “You never stop grieving.

It’s still hard after 11 years. It’s still hard. And it will always be hard. But you can’t let it … and she would never want any of us to ever wallow in that grief and let it take over our lives. She would never want that. She wasn’t like that.”

The 60-year-old actor went on to marry second wife Felicity Blunt in 2012.

Stanley and the literary agent, 38, were introduced to each other at Felicity's sister and his 'The Devil Wears Prada' co-star Emily Blunt's wedding to actor John Krasinski in 2010.

A year later, the couple were engaged and they have son Matteo, six, and daughter Emilia, two, together.

The 'Witches' star previously opened up on losing Kate and how "sad" he is that their children didn't get to spend more time with their "extraordinary" mother.

He said: "There's all the blaming of yourself, which you can't do, but you kind of do. I'm sad for Kate that she can't be here, and I'm sad for my children that they didn't have the opportunity to spend more time with her because she was an extraordinary person."
