Supermodel Kate Moss has an important condition when she signs modelling contracts - she insists on scheduling regular cigarette breaks.

The British beauty insisted on a clause in her contract with make-up brand Rimmel when shooting a campaign for the company last week (ends11Oct13), allowing her a cigarette every 15 minutes.

A source tells Britain's The Sun newspaper, "Kate is actually a dream to work with compared to a lot of high profile models. But her one major stipulation is that she has extremely regular fag (cigarette) breaks."
