Editor is embarrassed luvvy? (8)
I believe the answer is:
redactor
'editor' is the definition.
(I know that redactor is a type of editor)
'embarrassed luvvy?' is the wordplay.
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'luvvy?' becomes 'actor' (luvvy can informally mean an actor).
'red'+'actor'='REDACTOR'
'is' is the link.
(Other definitions for redactor that I've seen before include "someone to supervise church magazine?" , "Editor" , "literary organiser" , "One needs to make some changes" .)
