Kate, who has three children, has previously revealed that she does not have social media in her house. Last year she said: “ We're not a big deviced-up household."

"We don't have any social media, nothing like that."

She has also been outspoken about body image and her experiences as a young woman in Hollywood.

In an interview in 2008 she told Vanity Fair of trying to break into acting: “I was fat. I didn’t know any fat famous actresses.”

“I just did not see myself in that world at all, and I’m being very sincere. You know, once a fat kid, always a fat kid.”
