Although initial reports claimed that Heath Ledger died from a drug overdose - accidental or otherwise - now it appears that they might have been way off the mark.

Because now sources apparently close to the investigation into Heath Ledger's death suspect that he may have died because his heart just stopped. Whether it was a heart attack or something else - or whether these natural death claims are completely inaccurate - remains to be seen. But if it is true, then at least Jack Nicholson was wrong the other day.

And that's always heartwarming news.
