Reportedly lazy superstar (4)
I believe the answer is:
idol
'superstar' is the definition.
(I've seen this before)
'reportedly lazy' is the wordplay.
'reportedly' shows a homophone (sound like).
'lazy' becomes 'idle' (similar in meaning).
'idle' sounds like 'IDOL'.
(Other definitions for idol that I've seen before include "Darling" , "Graven image or worshipped person" , "Something worshipped" , "As before, fake" , "someone admirable" .)
