The BBC has confirmed that the 27-year-old pop star was found dead in her London apartment. Winehouse rose to international acclaim in 2006 with the breakout album "Back to Black," featuring her now tragic signature song "Rehab." "Back to Black" went multi-platinum and earned Winehouse five Grammys. She had long struggled with substance abuse and mental health issues. Winehouse cancelled her European comeback tour in June following a disastrous show in Belgrade in which the singer was obviously under the influence. The cause of death remains unknown. Winehouse now belongs to the infamous 27 Club.
