Good one about female artist's heavenly pair? (6)
I believe the answer is:
gemini
'heavenly pair?' is the definition.
(I've seen this in another clue)
'good one about female artist's' is the wordplay.
'good' becomes 'g' (abbreviation).
'one' becomes 'i' (Roman numeral).
'about' is a charade indicator (letters next to each other).
'female artist' becomes 'emin' (British artist Tracey Emin).
'i' put after 'emin' is 'emini'.
'g'+'emini'='GEMINI'
(Other definitions for gemini that I've seen before include "Twins star sign" , "House" , "set of twinklers" , "Sign of the Twins ( 6)" , "Third sign of the Zodiac" .)
