Kate Moss has been helping Colin Farrell staying clean.The Hollywood Wildman was in Miami on a two day break from rehab for a reported addiction to painkillers.An onlooker told Britain's Daily Star newspaper: "Kate and Colin started chatting around the pool at the Raleigh Hotel and she asked him how he was coping."He said he was getting there. It's early days for him but Kate's shown him the way and that's got to be a help."Meanwhile, supermodel Moss will not be prosecuted over allegations of cocaine use.The shamed star - who lost several lucrative modelling contracts and checked into rehab after images of her allegedly taking cocaine were published last year - jetted into the UK to be quizzed by cops earlier this month.But lawyers have now decided there isn't enough evidence for a case.

An insider is quoted in Britain's The People newspaper as saying: "All the police have are pictures of her taking a white substance.

"They have not found any cocaine and no admissions have been made. Photos are not enough by themselves to build a case."
