Be a socially acceptable lover (4)

I believe the answer is:

beau

'lover' is the definition.
(I know that beau is a type of lover)

'be a socially acceptable' is the wordplay.
'socially acceptable' becomes 'u'.
'be'+'a'+'u'='BEAU'

(Other definitions for beau that I've seen before include "Male admirer; dandy" , "An old-fashioned boy friend (4)" , "Sweetheart" , "Dandy - attentive companion" , "Handsome man" .)

I've seen this clue in The Globe and Mail.
