Whitney's death 'an example to us all': Washington

Denzel Washington thinks Whitney Houston's death is an "example to keep it together".

The 57-year-old actor believes his friend - who was found dead in the bathtub in her Beverly Hills hotel room in February - didn't realise the terrible toll her addiction to cocaine and crack had taken on her and should be a warning to all actors and musicians not to be seduced by the dark side of fame.
