A party gets journalist embarrassed (7)
I believe the answer is:
abashed
'embarrassed' is the definition.
('abash' can be a synonym of 'embarrass')
'a party gets journalist' is the wordplay.
'party' becomes 'bash' (term for a party or celebration).
'gets' means one lot of letters go next to another.
'journalist' becomes 'ed' (short for editor).
'a'+'bash'+'ed'='ABASHED'
(Other definitions for abashed that I've seen before include "Feeling uneasy" , "Disturbed" , "'Self-conscious, embarrassed (7)'" , "Ill at ease" , "shamed" .)
