Drunken star dies in accident (8)
I believe the answer is:
disaster
'accident' is the definition.
(disaster is a kind of accident)
'drunken star dies' is the wordplay.
'drunken' indicates an anagram.
'star'+'dies'='stardies'
'stardies' with letters rearranged gives 'DISASTER'.
'in' is the link.
(Other definitions for disaster that I've seen before include "Star dies (anag)" , "awful situation" , "Great tradegy or cataclysm" , "Calamity, sudden great misfortune" , "Event causing great damage" .)
