I believe the answer is:

'west of old hollywood' 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 "Girl" , "- West, US film actress" , "The first Hollywood blonde femme fatale, . . . West" , "-- West, C-twenty actress" , "- - West, life-jacket" .)
