American actress Brittany Murphy, who died suddenly at age 32, was buried on Christmas Eve with a private ceremony at a cemetery in the Hollywood hills, AFP reported.
The star of hit films such as "Clueless," "Just Married" and "8 Mile" died Sunday 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 Thursday at Forest Lawn Memorial Park with only a handful of family and friends, RadarOnline.com reported.
Murphy's husband, screenwriter Simon Monjack, has shot down suggestions that drugs were responsible for his wife's demise, in an interview Tuesday with People magazine.
He said instead that she had been ill for several days before her death.
TMZ.com, the entertainment Web site that broke the news earlier this year of the death of Michael Jackson -- who is also buried at Forest Lawn -- reported that multiple prescription drugs were found at Murphy's home on Sunday.
The Web site cited notes made by an investigator from the Los Angeles County Coroner's office as the source of the information.
According to the notes, a check of nightstands at Murphy's home "revealed large amounts of prescription medication in the decedent's name," as well as in the names of her husband, her mother and others.
The medications included painkillers, anti-depressants and anti-anxiety drugs, the report said.

32세로 요절한 미국 여배우 브리타니 머피가 크리스마스 이브인 24일 로스앤젤레스에 위치한 포레스트 론 공원 묘지에 안장됐다고 AFP가 보도했다.
장례식은 철저히 비공개로 진행됐다. 머피의 대변인은 "머피의 유족이 조용한 장례식을 원했다"며 "가족과 가까운 지인들만 모인 자리였다"고 설명했다.
머피는 지난 20일 갑작스런 심장마비로 사망했지만, 공식적인 사망 원인은 몇 주가 지나야 나올 것으로 보인다.
머피의 남편인 극작가 사이몬 몬작은 피플지와의 인터뷰에서 약물중독 가능성을 일축하면서 사망 전 수주 동안 그녀가 아팠다고 전했다.
그러나 연예 사이트 TMZ닷컴은 머피의 집에서 각종 치료용 약품이 발견됐다고 보도했다.
