Supermodel Naomi Campbell has said that she feels that she has paid her dept to society by doing community service.

Campbell wrote in her diary during her enforced stint as a toilet cleaner, �I find solace in sweeping. I have the time to think. Just have, you know, peace.

She adds, �I�m such a controlling person. Some people can handle a drink or a line of cocaine. For me, it�s all or nothing so it has to be nothing.�

These and other diary extracts will be published in the forthcoming issue of W magazine.

The catwalk star spent five days cleaning toilets earlier this year after being found guilty of hitting her maid with a mobile phone during a rage.
