Actress Longoria (3)
I believe the answer is:
eva
'actress longoria' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eva that I've seen before include "- - , nee Braun" , "Braun, Brick or Peron" , "- Peron, Evita" , "Dame - - Turner, soprano" , "Dame - - Turner, 15" .)
