Kate Moss is furious that fiance Pete Doherty has been hanging around his junkie crew again lately, and has finally laid down the law: either stop seeing them, or you're dumped.

Doherty, as you may recall, has been involved in a string of bad behavior in recently months. His latest debacle was this past weekend, during which he was arrested for the possession of a substance believed to be crack cocaine. Two of his buddies were with him at the time of the arrest, and were also arrested.

Kate has stopped wearing her fiance's ring since issueing the ultimatum. Kate sees these friends as a bad influence on her lover, and even Pete's Babyshambles bandmates agree with Kate on this one. They too see the friends, two in particular (The General and Peter Wolfe), to be a particularly bad influence on Doherty, who is trying to keep the needles out of his arms and off of smack.

Doherty has also been seen hanging around with groupies lately, which comes as another blow to Kate. He's got a supermodel girlfriend/fiance, and even that doesn't seem to be enough for him.
