The ‘Celebrity Skin’ singer – whose recent frail and thin appearance has caused concern – admits she has spoken to doctors about her dramatic weight loss and is determined to get healthy again. Speaking about her diagnosis two weeks ago, she said: “The doctor gave me a massive shot of vitamins and told me to start eating.

“Seriously, I want to get fatter. You know, when I was 192lbs I thought I looked hot. I’m serious about putting on weight – I want to get curvy. I know I’ve got too skinny. I want to sort it out.”

Courtney – who admits she was shocked to learn she weighs just 118lbs, and is underweight for her 5ft 10in frame – has blamed the stress of the alleged fraud of $200 million from her late husband Kurt Cobain’s estate for her weight loss.

She added: “I need to start working out again. It’s the stress – you have no idea what it has been like these last few months. I need to get to the bottom of this fraud, I need answers.

“I have had to escape from Los Angeles, I can’t cope there any more.”

The 44-year-old star is staying in New York and relying on the support of close pals including Sting, his wife Trudie Styler, and Gwyneth Paltrow.

She added to Britain’s Grazia magazine: “I have great friends, they have been looking after me since I was diagnosed with malnutrition. This is one of the reasons I came to New York, to visit friends who can cook for me.

“I am a big fan of Gwyneth’s Goop website, I’m trying to do the nourish yourself on the inside thing.”
