Good looking American robber (6)

I believe the answer is:

bonnie

This clue is a double definition.

'good looking' is the first definition.
(bonnie means pretty or good-looking)

'american robber' is the second definition.
(as in Bonnie and Clyde)

(Other definitions for bonnie that I've seen before include "attractive to northerners" , "Pretty" , "- - Prince Charlie" , "One of two gangsters" , "The Young Pretender" .)

I've seen this clue in The Guardian.
