Naomi Campbell gives beauty tips, says she 'only really eats once a day'

Supermodel Naomi Campbell has revealed she 'only really eats once a day'.

The star, who turns 50 next month, it's been learnt.

According to The Sun, Naomi said: 'I eat my lunch. Lunch is my dinner, because I really only eat once a day.'

Speaking about what she does on 'treat day' Sunday, she said: 'Sunday is my treat, so I’ll make desserts, my cakes and puddings.'

Naomi refrains from using dairy and gluten in her cooking, and has admitted in the past to fasting for days prior to a fashion show.

'I eat when I feel like it and I don’t starve myself. If I want to do a day of just not eating, I do it and just do water or juice. Depends how I feel. In the heat, sometimes I just want to do juice.

'It’s never planned. It could be one day, it could be two days a week. It’s just when I feel like doing it.'
