Murphy:

American actor Brittany Murphy, who died suddenly at age 32, has been buried with a private ceremony at a cemetery in the Hollywood hills, according to local reports.

The star of hit films including Clueless, Just Married and 8 Mile died Sunday (local time) of apparent cardiac arrest, but an official cause of death will not be released for several weeks as coroners await the results of toxicology tests.

Murphy was laid to rest in a "strictly private" service on Christmas Eve (local time) at Forest Lawn Memorial Park with only a handful of family and friends present, RadarOnline.com reported.

While there has been speculation drugs were responsible for Murphy's death, these have been shot down by her husband, screenwriter Simon Monjack.

He told People magazine she had been ill for several days before her death.

The cemetery where Murphy was interred is the final resting place of several Hollywood legends, including actors Bette Davis, Lucille Ball, Gene Autry and Buster Keaton.
