She isn't dead, I've checked the BBC news site, surely there would be news.

I actually established that she wasn't dead approximately 10 minutes after posting this thread.

There is an easy way to establish a celebrity's biological function, check their wikipedia page for a date of death.

It's all a conspiracy to make people think she's still alive. If people knew she was dead, they wouldn't watch as much celebrity news (they'd still watch a heck of a lot, just not as much as they do now), so those who know the truth have been perpetuating this lie. It's kind of like Weekend at Bernie's.

funny movie

The sequel certainly is, i nearly bust my sides watching it i seem to recall.

She's alive.  I found some stuff on her dated back in 2007 when a sculptor made a sculpture of her (and her dog) dead in a car crash.  It was a bit of bad taste, but it seems ever since now and then we get comments popping up in various places on the internet from people who have just found it and assumed she was actually dead.
