Brittany Murphy

's family members say words can't express the devastation they felt when they laid the 32-year-old actress to rest at a private funeral on Christmas Eve.

The service stretched into the evening as a Christian minister and a rabbi presided, and guests sang "Amazing Grace" at the grave site at Forest Lawn Memorial Park in the Hollywood Hills, where Liberace, Bette Davis, Lucille Ball, Gene Autry, and Freddie Prinze also are buried.

"A bright light that lit the world is forever dimmed, but will live on in the hearts of those that Brittany touched," her family said in a statement, according to the Associated Press.

"Brittany was an incredibly loving and passionate person and an artist to her core."

The intimate gathering was "very nice, very respectful," said longtime family friend Alex Ben Block.

He said that Murphy loved Christmas and that it was ironic that she was buried on Christmas Eve.

Her husband, Simon Monjack, talked about their relationship and called her his best friend and soul mate.

The two married in 2007.

Her closest friends and her cousin also recalled their favorite memories of her.

Murphy, who appeared in Clueless and 8 Mile, died Sunday after collapsing at her Hollywood Hills home. Authorities do not suspect foul play.

An autopsy was inconclusive.

The coroner is awaiting results of toxicology and tissue tests before determining an official cause of death.
