'singer' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'lucky liegeman entertains' is the wordplay.
'entertains' indicates a hidden word (the answer is welcomed or entertained by the clue).
'KYLIE' is hidden in the letters of 'lucky liegeman'.

Can you help me to learn more?

(Other definitions for kylie that I've seen before include "Aussie singer" , "Type of boomerang" , "returning missile" , "Dannii M's older sister" , "-- Minogue, Australian singer" .)
