Lager girl? (6)
I believe the answer is:
stella
This clue is a double definition.
'lager' is the first definition.
(Stella Artois)
'girl?' is the second definition.
(Other definitions for stella that I've seen before include "- Gibbons (Cold Comfort Farm)" , "Swift alias for Esther" , "Paul McCartney's daughter" , "woman" , "Swift favourite" .)
