Diana of the Supremes (4)

I believe the answer is:

ross

'diana of the supremes' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for ross that I've seen before include "US singer Diana" , "Wye town; Antarctic sea" , "Diana --, Motown singer" , "Diana - (Supremes)" , "- and Cromarty, former Scottish county" .)

I've seen this clue in the LA Times and the USA Today.
