Amy Winehouse Dies: Dead for up to Six Hours, Says Source [PHOTOS & VIDEO]

Amy Winehouse died on Saturday, for what rumors are saying was due to binge drinking and taking ecstasy -- though this has not been confirmed.

Reports say no drugs were found near Winehouse in her home in Camden, London. The cause of death remains unknown.

When police found the singer, it reportedly appeared she had already been dead for up to six hours. She was found alone in her bed, after telling a bodyguard that she was going to sleep, say unconfirmed sources via TMZ.

"She was in her bedroom after saying she wanted to sleep and when he went to wake her he found she wasn't breathing," said Chris Goodman, a friend and rep for Winehouse, reports TMZ.

Police have yet to report the cause of death, and say the rumors circulating her death are pure speculation. Until the autopsy is completed, the true cause of death will remain unknown.

"I am aware of reports suggesting this death is the result of a suspected drugs overdose," said Superintendent Raj Kohli of the Metropolitan Police, "but would like to re-emphasize that no post-mortem has yet been done and that it would be inappropriate to speculate on the cause of death.

"At this early stage it is being treated as unexplained and there have been no arrests in connection with the incident," he added.

Her Music Lives on

Like so many artists before her, the tragic news of her death has piqued a mass interest in the singer's music. Before her death, Winehouse only released two complete albums, but since 2006, the singer had been periodically working on a third unreleased album.

The Telegraph reports that sources say the singer's third album contains "a lot of material." It will be up to Winehouse's family to decide if the album is released or not.

"It is inevitable that her death will elevate her reputation and that there will be a third record released," said Phil Alexander, editor-in-chief of Mojo magazine, via the Telegraph.

Stars Pay Their Respects

On Monday, Katy Perry said on Good Morning America that her "heart felt really sad" after hearing news of Winehouse's death.

"My husband, who's been clean and sober for almost nine years, you know, I see him working a program and working on himself every single day," Perry said.

Best friend and fellow singer Kelly Osbourne, reportedly tweeted her disbelief on Saturday.

"I can't even breath right now i'm crying so hard I just lost 1 of my best friends. i love you forever Amy and will never forget the real you!"

Stars took to Twitter to tweet their respects to Winehouse, including Rihanna and Jessica Alba.

Rihanna: "I am genuinely heartbroken about this," and "Dear God have mercy!!! I am SICK about this right now!"

Jessica Alba: "So sad about Amy Winehouse- she was so talented. Really tragic."

A shrine of flowers has been made outside the home of the singer, where fans can pay their respects. Flowers, pictures, and even beer cans can be found at the shrine.
