Female stars making appearances (5)
I believe the answer is:
faces
'appearances' is the definition.
(face is a kind of appearance)
'female stars' is the wordplay.
'female' becomes 'f' (abbreviation).
'stars' becomes 'aces' ('ace' can be a synonym of 'star'**).
'f'+'aces'='FACES'
'making' is the link.
(Other definitions for faces that I've seen before include "Mugs" , "Meets defiantly - moves head accordingly" , "With 1a [NEW], TV talent show" , "Confronts" .)
