Amy Winehouse blames it on Satan

Amy Winehouse blamed her drug habit on the devil during a furious rant.

The troubled singer – bizarrely dressed in only skimpy black shorts and a lace bra – was in a West London recording studio attempting to pen tracks for her forthcoming third album when she became incensed at her uninspired efforts.

Amy, 25, only managed to play a repetitive tune using two notes on her £3,000 guitar and eventually became so frustrated she smashed up the instrument and began screeching that Satan was giving her drugs.

An eyewitness said: “She lost it.”

This latest incident has prompted fears for Amy’s mental health again.

Earlier this month, it was reported she had threatened to kill herself with a knife because she was missing her incarcerated husband Blake Fielder-Civil, who is currently serving a 27-month sentence for grievous bodily harm and perverting the course of justice.

Last month, the Rehab singer made a shambolic appearance at London’s Berkeley Square Ball – an annual charity event in aid of The Prince’s Trust.

Amy was supposed to sing backing vocals for her 12-year-old goddaughter Dionne – who was performing at the event in a bid to launch her music career – but only managed to mumble a few words.

Later, she reportedly hit out at a fan who asked for an autograph.

She was heard sobbing: “This isn’t a life – it’s a mess. Life can’t go on. I can’t do this any more.”

Meanwhile, Mark Ronson has revealed the name of the track he and Amy are covering for a tribute album to legendary producer Quincy Jones.

The pair are lending their talents to You Don’t Own Me, which was originally a hit for 60s singer Leslie Gore.
