Supermodel Campbell or actress Watts (5)
I believe the answer is:
naomi
I believe this clue is a double definition.
'supermodel campbell' is the first definition.
(I've seen this in another clue)
'actress watts' is the second definition.
(I've seen this in another clue)
(Other definitions for naomi that I've seen before include "- - Campbell, supermodel" , "Ruth's mother-in-law (Old Testament)" , "OT female" , "Ruth's mother-in-law (Bible)" , "mother- in-law" .)
