Fan club's focus (4)
I believe the answer is:
idol
'fan club's focus' 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 "Superstar; graven image" , "Graven image (sometimes false?)" , "Person who is the object of intense admiration as by fan club" , "pop star" , "loved one" .)
