Troubled British singer Amy Winehouse has been found dead in her north London home, according to a Metropolitan Police spokesman.

She was only 27.

London Ambulance Service said it was called to a home in Camden north London, but were unavailable to save her life.

The cause of death has not yet been determined, but Winehouse’s adult life had been marred by deep problems with drug and alcohol addictions. She had recently withdrawn from performing in a European comeback tour. While singing in Serbia, she was jeered at by fans for appearing to be inebriated.

But there were successes, too, Gifted with an otherworldly voice, her debut album, Frank, released when she was only 20 in 2003, gave her wide acclaim. By 2006, she gained global stardom with her smash album Back to Black, which won five Grammy Awards.

Saran Brown, wife of former British Prime Minister Gordon Brown, wrote on Twitter about Winehouse’s death: “It's deeply sad - the most completely tragic waste of talent that I can remember.”

Daily Telegraph music critic Neil McCormick tweeted: Sad sad news of Amy Winehouse - great talent, extraordinary voice, and tragic death, condolences to her family, she tweeted.

Fearne Cotton, a DJ on BBC wrote: Can not believe the news. Amy was a special girl. The saddest news.
