Ke$ha's mother has been her most vocal supporter since the singer checked into rehab for an eating disorder last month.
And while the Tik Tok singer is being treated for anorexia and bulimia, her mum Pebe Sebert has revealed the extent of her daughter's illnes, saying that relentless online bullying contributed to her daughter's condition.
Ke$ha's disorder had deteriorated so badly that she suffered from health conditions normally associated with someone who had suffered a heart attack.
"I've watched my beautiful, self-confident, brilliant daughter be berated and ridiculed for her looks and weight to the point that she almost died," she told People magazine in an exclusive interview.
"The doctors told me her blood pressure and sodium levels were so low, they'd never seen it that low except with someone who'd had a heart attack or stroke. They said it was a miracle she hadn't already dropped dead on stage."
Ms Sabert explained that her daughter has battled with body image issues since she was a teenager, but signing for a record label at the age of 18 put her under such intense scrutinty.
"One time on a conference call, Sonenberg [her former manager] was screaming, 'You need to lose weight! I don't care what you do ... take drugs, not eat, stick your finger down your throat'!"
"Ke$ha was just weeping. She drove around afterward thinking about killing herself."
Many of the award-winning singer's inner circle were so concerned for the welfare that they would often follow her into the bathroom after a meal.
"She could throw up really quickly and quietly. She'd even take a bag in there so no one could see her bent over the toilet. She was really sneaky," she added.
"She called me and admitted how much she'd been throwing up, and I just said, 'Okay.' I called some centres and Ke$ha agreed to talk to them and liked what they said. She basically cried until we got there three days later." (Ke$ha is being treated at the female-only facility Timberline Knolls, outside of Chicago.)
