Troubled pop star Britney Spears has found an unlikely source of support - listening to Amy Winehouse's latest album. Spears has been pictured around Los Angeles clutching the equally troubled singer's much acclaimed Back To Black LP. The two stars have a lot in common as they both recently suffererd very public breakdowns. Spears' behaviour has become more erratic after she lost custody of her children to ex-husband Kevin Federline last year (07), whilst Winehouse sparked fears for her health amid reported battles with drugs after her husband Blake Fielder-Civil was charged with perverting the course of justice and sent to prison at the end of 2007.
