Much-admired celebrity (4)
I believe the answer is:
idol
'much-admired celebrity' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for idol that I've seen before include "Graven image (sometimes false?)" , "Personal hero" , "Worshipped statue" , "A graven image or object of adoration" , "loved one" .)
