'party girl' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?

'out late with ted' is the wordplay.
'out' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'late'+'ted'='lateted'
'lateted' is an anagram of 'LADETTE'.
