Paid actor supplying cues (4)
I believe the answer is:
feed
'paid' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
(Other definitions for feed that I've seen before include "Give (or take) nourishment" , "Given payment" , "take grub" , "Fodder" , "Eat; pass (a ball) to another player" .)
