While the world is still trying to get its head around yesterday's sudden death of Heath Ledger, it's already time to start figuring out exactly what killed him.

The autopsy on Heath Ledger's body will take place today, meaning that it shouldn't be long before we know which of the conflicting stories about Heath Ledger's death - was it suicide? An accidental overdose? Pneumonia? - is most accurate.

Meanwhile, tributes have been pouring in from Heath's admirers, friends and family.

Heath Ledger has been found dead in his Manhattan apartment.

The unconcious body of the 28-year-old Aussie actor was discovered by his housekeeper on Tuesday afternoon.

If you discovered that Ike Turner died of something boring like pneumonia or old age or a heart condition, you'd be pretty upset.

After all, this is Ike Turner - inventor of rock and roll and wife-beater extraordinaire - we're talking about. Surely Ike Turner's death had to be as spectacular as his life. 

Well it was, provided that 'Massive Cocaine Overdose' is spectacular enough for you. And, unless you were hoping that Ike Turner's death was caused by a giant robot from outer space exploding him with its death rays, hopefully this will do.

Dennis Quaid's newborn baby twins are lucky to be alive - it wasn't so long ago that they were being injected with doses of blood-thinner 1,000 times larger than normal.

But although his new son and daughter survived the giant Heparin overdose - and are thought to be recovering well - Dennis Quaid is still thirsty for revenge. That's why Dennis Quaid and his wife Kimberly Buffington are suing Baxter Healthcare Corp, which manufactures Heparin, for £50,000 in a product liability lawsuit. It shows just how angry Dennis Quaid must be to pursue Baxter through legal paths, because in the past he's resolved any outstanding medical difficulties by shrinking himself down to a sub-atomic level and injecting himself up Martin Short's arse.

As Innerspace-loving children, we were led to believe that there was nothing that Dennis Quaid couldn't solve by drunkenly shrinking himself down to a speck and flying around people's bloodstreams singing Sam Cooke songs.

But, in truth, even when you've fictionally been injected into Martin Short's buttocks you still have to cope with immense tragedies like the rest of us. That's something Dennis Quaid had to come to terms with pretty quickly this week when his newborn twins were accidentally injected with 1,000 times more of the anti-coagulant drug Heparin than usual. However, the good news seems to be that Quaid's twins are recovering well and showing "no adverse reactions." Hopefully this news will put an end to what must have surely been one of the most traumatic times Dennis Quaid's life.

True, the second-most traumatic time was when Dennis Quaid read the The Day After Tomorrow script and realised he'd be paid to out-run some ice, but that shouldn't diminish the relief he should be feeling now.
