Hollywood's ____ West (3)
I believe the answer is:
mae
'hollywood's west' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mae that I've seen before include "The first Hollywood blonde femme fatale, . . . West" , "Woman" , "-- West, C-twenty actress" , "- West, US film actress" , "Girl" .)
