Kate caught taking illegal substance on stage

She was caught on camera flouting Ireland's strict smoking ban at a concert where her boyfriend Pete Doherty was performing with his band Babyshambles.

The supermodel, wearing the skimpiest of black dresses, was singing on stage with Doherty when she took conspicuous puffs on a cigarette which was dangling in her hand.

Doherty was also seen to be smoking constantly throughout the gig at the Music Factory, in Carlow, Co Carlow. Moss, 32, now faces a 3,000 euro fine - about £2,000 - for what would appear to be a violation of Ireland's smoking ban, which came into effect in March 2004.

Not that a successful prosecution is guaranteed. The last time Moss was caught misbehaving on camera - apparently snorting cocaine during a Babyshambles studio recording session - she subsequently escaped charges.

While prosecutors suspected that she was taking an illegal substance, they could not be sure whether it was a class A drug such as cocaine or a lesser drug such as amphetamines.

The result: after a nine-month police investigation, Moss walked free and her earnings sky-rocketed.

She and Doherty are rumoured to be planning to get married but looked less than lovestruck last night in Dublin.

Doherty, 27, who has just completed a drugs rehab stint at The Priory clinic, was sporting a black eye and looked exhausted - this was before he had even gone on stage at the Ambassador Theatre for a second gig.
