What do you think caused Brittany Murphy to die of cardiac arrest?

We'll find out more in the next few days when doctors know more too. I don't think it was drugs as she isn't like other Hollywood actresses and she's never been as skinny as others (i don't think she was as skinny anyway) so it can't be an eating disorder. I really hope she didn't go down that road. Maybe it was her heart and she had problems with it but never revealed it publicly? Brittany Murphy is one of my favorite actresses and i can't believe that she is dead! I have loads of her films on DVD as she is a really funny comical actress. My favorite films of hers are Just Married & Clueless. I can't believe she's gone and i hope she's now in a better place. Lisa Michelle x x lol x x
