I went on Accutane, which is very strong. Your sebaceous glands dry up, you can't exercise, and you have very dry lips. But it was a miracle, and it worked.

I'm very conscious about putting good food into my body. Years ago, I went to see an amazing healer called Allah, who could read your body. She told me that I can't absorb vitamins very well, and I have to eat the right things to get my vitamins. I've always remembered that.

Don't look at your legs and think: 'They're fat.' Think: 'These things carry me around all day, and I don't have arthritis. Oh, and I've got great ankles.'

The first time I was given money to shop for myself, I was 13 and staying with my godmother in New York. I went to Clinique and bought the three-step acne programme and felt so grown-up.

At school, I was only allowed four sweets every Wednesday, so I've developed an addiction.

Ottolenghi sells lots of delicious sweet things, but my daily addiction is their unbelievable dark chocolate salted caramel biscuits. They're the best things in the world - I go through half a packet every night. I bring them out after pudding at dinner parties.
