British singer Amy Winehouse, known for her smoky soul voice and her struggle with drink and drugs, has been found dead at her flat in north London. She was 27 years old.

The Grammy award-winning soul singer with her trademark beehive battled with addictions that she documented in her hit single "Rehab". Her death is being treated as unexplained, and enquiries into the circumstances of her death are still continuing, Scotland Yard said.

Back to Black
Winehouse rocketed to fame after winning five Grammy awards off the back of her 2006 second album "Back to Black" and the hit single "Rehab". In the run-up to her return to live performance, she spent a week earlier this year at an addiction treatment clinic in London, reportedly at the suggestion of her father, Mitch, who was concerned that she was drinking too much before her shows.

Booed
But she pulled out of her European comeback tour following a disastrous opening performance in Serbia on June 18. She appeared to be too drunk to sing and was greeted with booing. Some 20,000 people were gathered for the highly-promoted concert at the sixth-century Kalemegdan fortress in Belgrade, but many soon left.

During the concert, which lasted about 90 minutes, Winehouse could only mumble some of the lyrics, failing to follow her band. Winehouse left the stage twice, with many fans showing their displeasure despite her band's attempts to calm the crowd.

Beehive
She had also been scheduled to perform in Istanbul, Athens, Bilbao in Spain, Locarno in Switzerland, Italy's Lucca festival, Switzerland's Paleo Festival in Nyon, Nova Jazz and Blues Night in Wiesen, Austria, and Poland's Bydgoszcz Artpop Festival.

Known for her distinctive voice and beehive hairdo, Winehouse's debut album "Frank" was released in 2003 and brought her wide acclaim. It went triple platinum in Great Britain.

The follow-up, "Back to Black", was a worldwide smash hit, reaching number one in Britain and number two in the US charts. It went six times platinum in Britain and double platinum in the United States.

Tempestuous
She married Blake Fielder-Civil in Miami in May 2007 but they had a tempestuous relationship. He spent part of their marriage behind bars for a vicious attack on a pub landlord and a subsequent attempt to cover it up. They divorced in July 2009.
