Kerry Katona is following up her car crash performance on This Morning with a tongue lashing about Angelina Jolie and Brad Pitt.

The former Atomic Kitten star criticised the Changeling star's parenting skills after Angelina openly admitted buying her son Maddox a knife.

Kerry tells OK!, “My daughter Molly is the same age and I would never even think about doing the same.

“I hate knives. Just because Angelina's mum took her to buy daggers when she was 11, it doesn’t mean she has to encourage her own kids.”

She adds, “She is totally wrong for Brad.”

Kerry's own parenting skills came into question when the star showed up for an interview yesterday on This Morning and proceeded to slur her words.

Kerry later blamed prescription drugs for her erratic behaviour.
