She's to be found east of Kentucky (5)
I believe the answer is:
kylie
'she's' is the definition.
'found east of kentucky' is the wordplay.
'found' becomes 'lie' (I've seen this before).
'east of' means one lot of letters go next to another (some letters go to the right of others).
'kentucky' becomes 'ky' (abbreviation).
'lie' put after 'ky' is 'KYLIE'.
'to be' acts as a link.
(Other definitions for kylie that I've seen before include "Dannii M's older sister" , "Type of boomerang" , "-- Minogue, Australian singer" , "returning missile" , "Aussie singer" .)
