Kerry Katona has broken her silence on her latest drugs scandal and admitted, “I have let my children down.”

In an interview with the Sunday Mirror the reality TV star – a former winner of I’m A Celebrity…Get Me Out Of Here! said she was “ashamed of her actions” after last weekend’s tabloids featured footage of her apparently snorting cocaine.

She added that she was planning to undergo treatment for her problems in an attempt to turn her life around.

“I am so sorry and so ashamed of my actions,” she told the paper. “I know I let everyone down – my fans, my family and people I work with. It was a moment of weakness and stupidity and I regret it terribly.

“No one forced me to do it, I’m a grown-up woman and I did it because I was very unhappy at the time and thought it might make me feel better about myself. I have been crying and been at my wit’s end since it happened.”

The scandal has seen Katona sacked as the face of supermarket chain Iceland- despite having already filmed Christmas commercials for them – while speculation is mounting that her ex-husband Brian McFadden may seek custody of their children Molly and Lilly-Sue.

“If any good can come out of this,” Katona added, “then let it be this – I would like to tell every man, woman and child in the UK that taking drugs only ever causes misery in the end.

“They don’t make you look cool, they make you look an idiot, and all your insecurities and self-hate – the main reasons I took them in the first place – are only made worse.”
