Stomach, belly (3)
I believe the answer is:
gut
I believe this clue is a double definition.
'stomach' is the first definition.
(I've seen this before)
'belly' is the second definition.
(informal term for the stomach or gut)
(Other definitions for gut that I've seen before include "Eviscerate" , "Natural violin string material" , "Remove innards from" , "Rip out (a place's) interior" , "Part of the digestive system" .)
