Kate Moss' mother has flown to Arizona to spend time with the shamed supermodel who is currently undergoing rehab at The Meadows Clinic.

LINDA MOSS will accompany her daughter in "family therapy sessions", part of the treatment she began after being caught by a British newspaper snorting cocaine.

A source tells London's Evening Standard newspaper, "Linda spoke to Kate every day while she was in New York when the story broke and spoke to her in Arizona as well.

"Kate does not really know who her friends are, but she knows she can rely on her mother."
