Lover once noisily kissed soldier perhaps in the club (9)
I believe the answer is:
expectant
'in the club' is the definition.
(both can mean pregnant)
'lover once noisily kissed soldier' is the wordplay.
'lover once' becomes 'ex' (an ex-lover).
'noisily' indicates a 'sounds like' (homophone) clue.
'kissed' becomes 'pecked' (pecking is a kind of kissing).
'soldier' becomes 'ant' (soldier is a type of ant).
'pecked' sounds like 'pect'.
'ex'+'pect'+'ant'='EXPECTANT'
'perhaps' is the link.
(Other definitions for expectant that I've seen before include "Waiting for something" , "Eager to see what happens" , "Hopeful" , "in the club" , "Anticipating" .)
