Gossip or hearsay (6)
I believe the answer is:
rumour
I believe this clue is a double definition.
'gossip' is the first definition.
(I know that rumour is a type of gossip)
'hearsay' is the second definition.
(I know that hearsay can be written as rumour)
(Other definitions for rumour that I've seen before include "Report of doubtful truth" , "Hearsay, gossip" , "Story going around" , "Information that may well not be true" , "buzz" .)
