Newly married lover (7)
I believe the answer is:
admirer
'lover' is the definition.
(admirer is a kind of lover)
'newly married' is the wordplay.
'newly' indicates an anagram.
'married' with letters rearranged gives 'ADMIRER'.
(Other definitions for admirer that I've seen before include "potential suitor" , "Married to suitor" , "Married to one who cherishes" , "One who cherishes, like boy friend" , "girlfriend?" .)
