Finished accepting desire for the leading lady (7)
I believe the answer is:
doyenne
'the leading lady' is the definition.
(I've seen this before)
'finished accepting desire' is the wordplay.
'finished' becomes 'done' ('done' can be similar in meaning to 'finished').
'accepting' means one lot of letters goes inside another.
'desire' becomes 'yen' (yen is a kind of desire).
'done' going around 'yen' is 'DOYENNE'.
'for' is the link.
(Other definitions for doyenne that I've seen before include "Prominent female in her field" , "Senior female member of a group" , "Senior lady in profession" , "Respected lady" , "Leading lady" .)
