The 35-year-old actress confesses she deals with unsightly outbreaks on her face by taking the essential amino-acid, but has to maintain it otherwise the pimples return.
She said: “I get breakouts on my chin – it’s a f**ker. Lysine helps massively with the skin. I definitely advise it. But you have to take a lot of it.”
She also has to make sure to exercise, doing Pilates to help keep her trim figure in shape.
Kate told Britain’s Vogue magazine: “Well, I’m 35 now. I’ve got to keep it together. I mean f**k, it really does start to happen doesn’t it? I’ve been doing a bit of Pilates and some running. A little bit of this and that.
“A part of, I suppose, my way out of everything, has been really taking care of myself.”
The British beauty also confesses she is not a person who enjoys going out shopping, claiming she “hates” the idea.
She said: “I don’t go shopping. I’m not one of those people who can do a day’s shopping. I’ve never been like that. Never, ever, I can’t. I really hate it.”
