Best Actress of 1987 (4)
I believe the answer is:
cher
'best actress of 1987' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cher that I've seen before include "1987 Best Actress Oscar winner for "Moonstruck"" , "US pop singer" , "US singer; dear (Fr.)" , "US singer/actress - French river/department" , "Moonstruck star" .)
