Supporter, devotee (3)
I believe the answer is:
fan
I believe this clue is a double definition.
'supporter' is the first definition.
(I know that supporter can be written as fan)
'devotee' is the second definition.
(I know that devotee can be written as fan)
(Other definitions for fan that I've seen before include "Manually wielded cooling device" , "Enthusiastic admirer as of pop star" , "Great enthusiast" , "Spanish women wave it to cool themselves" , "Devoted admirer or air cooler" .)
