Actress Jillian (3)
I believe the answer is:
ann
'actress jillian' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ann that I've seen before include "- Widdecombe MP" , "Ms Widdecombe" , "Girl" , "... Margret or Hathaway" , "- - Jones, 1969 Wimbledon champion" .)
