Relative of Connie Cezon (5)
I believe the answer is:
niece
'relative' is the definition.
(niece is a kind of relative)
'of connie cezon' is the wordplay.
'of' indicates the answer is hidden within the clue.
'NIECE' is hidden in the letters of 'connie cezon'.
(Other definitions for niece that I've seen before include "Preparation for curdling milk" , "Brother's daughter" , "Young female relative" , "Criminal" , "Son's cousin" .)
