Singer Baker (5)
I believe the answer is:
'singer baker' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anita that I've seen before include "-- Brookner, English novelist" , "- Loos (Gentlemen Prefer Blondes)" , "girl produced" , "-- Loos, US writer" , "eg Dobson or Roddick" .)
