Robbie: 'I nearly stabbed myself on LSD'

Robbie Williams has revealed that he wanted to stab himself while using the drug LSD.

The singer started having hallucinations after taking the illegal substance at the age of 16.

"It was at Shelley's [nightclub] where I had my first acid experience. We were in Golden Hill, in someone's kitchen probably," he wrote on his blog.

"I was given a tiny piece of paper to ingest. E's were too expensive for the Potteries. £15 - who could afford that? There was a band called The Prodigy performing that night and I thought they were really good.

"Afterwards we drove up to the garage and the police were on the forecourt. S**t, I thought. I want to go home, I'm scared. There is only one place I want to be - at home with my mum.

"So I decided to go downstairs and stab myself. Mum came out of her room and said, 'What are you doing?'

"I'm just going downstairs to stab myself – do you want a cup of tea?" the singer then told his mother.

Williams is reportedly currently in negotiations with Simon Cowell to become a judge on The X Factor.
