Photographer Corinne Day - who helped Kate Moss shoot to fame in the late Eighties - is gravely ill with a brain tumour.
The 44-year-old was diagnosed with the condition 13 years ago and was said to have overcome it.
The tumour returned aggressively two years ago, however, and Corrine's only option became specialist treatment in Arizona costing over £100,000.
An auction of her pictures - arranged by Kate Moss and her fashionista friends - raised funds for the therapy.
"Sadly, although they paid for Corinne's treatment, there has not been much change in her prognosis," a friend tells the Daily Mail.
"She completed the treatment in Arizona and came back to the UK just before Christmas. She is gravely ill and it is difficult for her to make plans, but she is just trying to remain positive about the situation. She is living each day at a time."
Corrine's photograph of 14-year-old schoolgirl Kate in her knickers and a pink vest top (pictured) was used in a spread for The Face magazine and became one of the supermodel's most memorable shoots.
