Superstar’s out of work, we’re told (4)
I believe the answer is:
idol
'superstar's' is the definition.
(I've seen this before)
'out of work we're told' is the wordplay.
'out of work' becomes 'idle' (I've seen this before).
'we're told' indicates a 'sounds like' (homophone) clue.
'idle' sounds like 'IDOL'.
(Other definitions for idol that I've seen before include "Something worshipped" , "Hero of screen or stage" , "Image of a god (not icon)" , "Honoured figure" , "someone admirable" .)
