Genuine, spontaneous (7)
I believe the answer is:
natural
I believe this clue is a double definition.
'genuine' is the first definition.
(thesaurus)
'spontaneous' is the second definition.

(Other definitions for natural that I've seen before include "Organic" , "Unaffected, normal in manner" , "Not man-made; off-white" , "Plain - lifelike" , "(In music) neither sharp nor flat" .)
