Amy Winehouse
The 'Back to Black' singer started drinking alcohol aged just 12 and her battles with substance abuse dogged her life until she passed away from alcohol poisoning aged 27 in 2011.
Her addictions worsened after meeting Blake Fielder-Civil - whom she was married to between 2007 and 2009.
Winehouse's manager Nick Godwyn told The Times newspaper: "Amy changed overnight after she met Blake. She just sounded completely different. Her personality became more distant. And it seemed to me like that was down to the drugs."
