According to a new report, actress Brittany Murphy may have died of natural causes.

The AP reports that the Los Angeles Coroner's office told them that it appears that Murphy died of natural causes and that they are looking into the actress' medical history. An official cause of death will not be announced for some time due to the need to perform toxicology tests, the AP reports.

Assistant Chief Coroner Ed Winter told the AP that Murphy apparently collapsed in the bathroom Sunday morning. He also told them that Murphy's family is cooperating with the coroner's investigation and that an autopsy is planned for Monday or Tuesday.
