Kerry Katona has recalled her horror of pulling a blade out of her mum's leg after she'd been stabbed by her boyfriend.
The Atomic Kitten alum, who has had a strained relationship with mum Sue in the past, called it a "terrible" memory.
She likened it to being held hostage by armed robbers in the home she shared with ex Mark Croft in 2007.
Writing in her New magazine column, Kerry, 38, said: "The incident brought back terrible memories of the time my mum's boyfriend stabbed her and I had to pull the blade out of her leg.
"Seeing men in my house with knives definitely triggered something in me."
Kerry was just 13 when she witnessed the violent attack - which saw the since deceased boyfriend attempt to slice her mum's ankles off.
"My mum got stabbed by her then-boyfriend – twice in the chest, in both breasts, in her leg and he tried to cut her ankles off," she previously told Now magazine.
That same year she was put into foster care after her mum was diagnosed with schizophrenia and lived with four different families while she was growing up.
Sue previously admitted tricking her then 14-year-old daughter into taking a mphetamines by pretending it was sherbet because she "thought it would be fun".
When Kerry appeared on Celebs Go Dating earlier this year she revealed that Sue left her dad for her granddad , so her dad became her own brother and her granddad became her dad when they married.
“My earliest memory is watching my mum slit her wrists, when I was three. She was a manic-depressive, and she self-harmed until I was 15," she told The Guardian in 2012.
“She’s got the marks all the way up her wrists, which is why I’ve got the names of my two elder daughters, Mollie and Lilly, tattooed on my own wrists.”
Kerry added: “I had to take on a lot as a child. We lived in Warrington and I went to eight schools, I had four sets of foster parents, lived in three refuges.”
