Lady-killer appearing in clubs as a star (8)
I believe the answer is:
casanova
'lady-killer' is the definition.
(I've seen this before)
'clubs as a star' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'star' becomes 'nova' (nova is a kind of star**).
'c'+'as'+'a'+'nova'='CASANOVA'
'appearing in' acts as a link.
(Other definitions for casanova that I've seen before include "Italian who wrote of his sexual exploits" , "18th century Italian lover" , "Notorious Italian womaniser of 18th century" , "An Italian Don Juan" , "Man noted for his amorous adventures" .)
