Photographers (9)
I believe the answer is:
paparazzi
'photographers' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for paparazzi that I've seen before include "Freelance snappers" , "Freelance photographers, from Italy" , "Italian freelance photographers, very intrusive" , "Press photographers" , "Photographers who pursue celebrities" .)
