"Look Who's Talking" actress (5)
I believe the answer is:
alley
'look who's talking actress' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alley that I've seen before include "space in US court" , "Passage between buildings" , "Narrow passage" , "Narrow lane; type of cat" , "Back lane" .)
