So it's official - an accidental overdose of sleeping pills, anti-anxiety medication, painkillers and other prescription drugs killed Heath Ledger.

The New York City medical examiner has declared that Heath Ledger died from “acute intoxication by the combined effects of oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine,” in a report that's just been released.

As sad as this news is, we should focus on the positives - not only can Heath Ledger's family continue with their lives knowing that at least it wasn't suicide, but Heath Ledger looks set for pub quiz immortality by being the answer to the question "Which celebrity cause of death would get you the highest score in a game of Scrabble?"
