Pop star (4)
I believe the answer is:
idol
'pop star' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for idol that I've seen before include "Object of worship (or love?)" , "Subject of adoration, may be graven" , "Effigy" , "Personal hero" , "Graven image or greatly admired person" .)
