LONDON -- The family of Amy Winehouse was preparing to hold a private funeral Tuesday for the singer, who was found dead last week at the age of 27.

Family spokesman Chris Goodman said the private service for family and close friends would be held later in the day at an undisclosed location.

The soul diva, who had battled alcohol and drug addiction, was found dead Saturday at her London home.

An autopsy held Monday failed to determine the cause of the singer's death. Police are awaiting the results of toxicology tests, which will take two to four weeks.

On Monday the singer's father, mother and brother visited the house where she died, thanking mourners who had left flowers and cards.

Father Mitch Winehouse said "Amy was about one thing and that was love."

"Her whole life was devoted to her family and her friends and to you guys as well," he told fans.

Winehouse released only two albums in her short career _ winning five Grammy awards for the second, "Back to Black" _ and often made headlines because of drug and alcohol abuse, eating disorders, destructive relationships and abortive performances.

Since her death, her records have re-entered album charts around the world, and tributes have poured in from fans and fellow musicians.

George Michael called her "the most soulful vocalist this country has ever seen," and soul singer Adele said she "paved the way for artists like me and made people excited about British music again."
