The family of Amy Winehouse is preparing to hold a private funeral 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 will be held Tuesday at an undisclosed location.

A day earlier, an autopsy 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.

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

On Monday her father visited the house and thanked mourners who had left flowers and cards. 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."
