Kerry Katona's mother Sue broke down in tears as she admitted to giving her daughter speed when she was just 14.

The Atomic Kitten star's parent appeared on national television on UK TV early morning show 'Good Morning Britain' on Tuesday morning (04.09.18) where she admitted that it was ''unforgivable'' of her to give Kerry, now 37, the Amphetamine as a teenager without telling her what it was, when Sue herself was abusing substances.

She told presenters Piers Morgan and Susanna Reid: ''It's not a nice thing that I done.

''It was embarrassing, dangerous, unforgivable. I was off me head when I done it.

''I worked in a pub, she was me mate not me daughter. It was totally, totally wrong.''

Whilst Kerry went on to battle with drug and alcohol addiction throughout her life, the 'Whole Again' hitmaker doesn't blame her mother, and believes she would still have taken them anyway as she thought it was the norm.

She said: ''If mum my hadn't given it to me, I would have done it anyway.

''I thought people who didn't do drugs were snobs. That's how it was for me.''

Kerry - who has 17-year-old Molly and 15-year-old Lilly-Sue with first husband Brian McFadden and 11-year-old Heidi and Maxwell, 10, with second spouse Mark Croft - said of her first time taking speed: ''I talk a lot anyway as it is. I was living with my foster parents at the time. I remember not being able to go to sleep.

''But everyone we were in the pub with were having a wonderful time. It became my normality.''

Kerry - who is estranged from third husband George Kay - first found fame as a member of the chart-topping girl group in the late 90s, but subsequently ran into money troubles as her life spiralled out of control.

The pop star - who suffers from bipolar disorder - previously admitted to surrounding herself with the wrong people during her career, although she's not ''ashamed'' of her personal struggles.

She said: ''I lost my money. I don't have money now. I got out of bankruptcy again in September but I feel good. I feel amazing.

''It was embarrassing as well. You could see that people around me who I was hanging out with at the time, all the hangers on just wanted me for my money and all the fame. The people I was buying drugs with you could see their delight they just wanted to bring me down. But I'm not ashamed.''
