Married excited fan (7)
I believe the answer is:
admirer
'fan' is the definition.
(an admirer is a fan of something)
'married excited' is the wordplay.
'excited' indicates an anagram.
'married' is an anagram of 'ADMIRER'.
(Other definitions for admirer that I've seen before include "One who cherishes, like boy friend" , "Hopeful lover?" , "Supporter or fan" , "Romantic adorer" , "One who thinks highly or romantically of" .)
