Actress Brittany Murphy, star of Hollywood films such as Clueless and 8 Mile, has died at age 32 after collapsing at home in Los Angeles.
Coroners said that Murphy, who was pronounced dead in hospital, appeared to have died of natural causes.
However, the official cause of death may not be determined for some time as toxicology tests are required.
Ashton Kutcher, co-star of the 2003 comedy Just Married, paid tribute to her as a "little piece of sunshine".
Murphy was pronounced dead at 1004 (1804 GMT) on Sunday at a hospital near Beverly Hills.
She had been taken there after the Los Angeles Fire Department responded to a call at the Hollywood Hills home she shared with her husband, British screenwriter Simon Monjack.
She is reported to have been found unconscious in the shower.
Assistant Chief Coroner Ed Winter said the authorities were looking into her medical history.
"It appears to be natural," he added.
Los Angeles police have opened an investigation into the death. - bbc news
