Worshipper of false gods (8)
I believe the answer is:
idolater
'worshipper of false gods' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for idolater that I've seen before include "Tailored for image worshipper" , "Strong admirer" , "Person who worships graven images" , "One worshipping graven image" , "Huge admirer" .)
