"London Ambulance Service were called to the scene. Life was pronounced extinct at the hotel.
"A post-mortem will be held in due course. Next of kin are in the process of being informed."
The US-born star was a good friend of Michael Jackson, and married Liza Minelli in 2002. The couple parted ways just over a year later, in October 2003.

As well as impressing viewers at home, David delighted his fellow campmates, and went on to be at usher at former Busted star Matt Willis's wedding.
