Friends of Kate Moss fear the model could be on downward anorexic spiral as she spends her days dieting on hot water and green leaves.
A gaggle of groupies from her British pad say Moss has "lost a half a stone over the past three weeks and is virtually not eating at all."
"Her skin is in a terrible state and her hair is ratty and unkempt," a source told the Daily Mail.
"Many of her close friends worry that she is too thin."
Her break-up with rocker Pete Doherty is the major reason for her downfall, alongside failed contract negotiations with Burberry and Agent Provocateur, the newspaper reports.
"Her professional and personal life hasn't been great of late and everyone has been telling Kate to put on a few pounds," the source said.
Revelations that Doherty may be back with his ex Irina Lazareanu — the same girl who Moss asked to model her Top Shop collection — have reportedly added to Moss's breakdown.
The Babyshambles front man checked into a rehab centre over the weekend, at a reported cost of $730-per-day.
Doherty was arrested last Monday after allegedly found carrying drugs after performing at a music festival.
The singer subsequently walked free after police failed to bring him before a court for breaching his bail conditions within 24 hours.
