Brittany Murphy’s death certificate has been released

The ‘Clueless’ actress - who was married to screenwriter Simon Monjack - was believed to have suffered a cardiac arrest at her home in Los Angeles when she passed away aged 32 on December 20. But the official document lists the cause of her death as “deferred” and the manner of death as “pending investigation”.

Her father Angelo Bertolotti, with whom she barely had a relationship, is also not listed on the certificate – instead it claims he is “unknown”.

The exact cause of death is expected to be confirmed when toxicology results are returned early February.

She actually recodrd an album in late 2009 and a music executive said: “People are definitely interested in Brittany and her story. Depending on what she may have recorded and what kind of quality it is, she could end up having a hit song or two” ala Aaliyah. It has been reported that tracks from the actress’ debut album may be released in 2010.

There has been a lot of speculation about Brittany's use of prescription drugs and weight issues. Ten different types of perscribed medication were confiscated from her bedroom after she was found collapsed in the shower by her mother.
