Father has new attractive female (5)
I believe the answer is:
siren
'attractive female' is the definition.
(sirens are seductive singers in Greek mythology)
'father has new' is the wordplay.
'father' becomes 'sire' (synonyms).
'has' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'sire'+'n'='SIREN'
(Other definitions for siren that I've seen before include "Hooter - femme fatale" , "Seductive woman" , "Seductress" , "Nymph supposed to have lured sailors to destruction on rocks" , "She tempts" .)
