Model Campbell (5)
I believe the answer is:
naomi
'model campbell' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for naomi that I've seen before include "Do I moan about Biblical Ruth's mother-in-law?" , "Girl's name, meaning "pleasant"" , "Relative of Ruth" , "woman's name" , "Ruth's mother-in-law (OT)" .)
