Incorporated paramour on easy street (2,6)
I believe the answer is:
in clover
'on easy street' is the definition.
(I've seen this in another clue)
'incorporated paramour' is the wordplay.
'incorporated' becomes 'inc'.
'paramour' becomes 'lover' (I've seen this before).
'inc'+'lover'='IN CLOVER'
(Other definitions for in clover that I've seen before include "Having life of ease" , "Enjoying prosperity or luxury" , "Sitting pretty" .)
