US actress Brittany Murphy died yesterday from heart attack at the age of 32.

Multiple sources told celebrity news website TMZ.com that she went into full cardiac arrest and despite multiple attempts, could not be revived.

Los Angeles Fire Department spokesman Devon Gale said emergency services were called to the house she shared with her British screenwriter husband Simon Monjack in Los Angeles at 8am local time.

According to reports, her mother Sharon Murphy discovered her daughter unconscious in the shower.

Paramedics determined that Brittany was in full cardiac arrest and immediately administered CPR.

They continued mouth-to-mouth as they sped to Cedars-Sinai Medical Center, several miles away from her home, but Brittany was pronounced dead on arrival at 10.04am on Sunday.
