An autopsy in the mysterious death of singer Whitney Houston is complete but the results have been withheld by the authorities pending toxicology report that will determine the cause of her death.

The toxicology report may take six to eight weeks but the officials are not ruling out any causes of death until the toxicology results. Foul play has been ruled out in the 48-year-old's death, whose body was found by a member of her entourage on Sunday.
