Celebrity journalist gawped (6)
I believe the answer is:
stared
'gawped' is the definition.
(gawp means to stare at something)
'celebrity journalist' is the wordplay.
'celebrity' becomes 'star' (a star is a celebrity or famous person).
'journalist' becomes 'ed' (short for editor).
'star'+'ed'='STARED'
(Other definitions for stared that I've seen before include "Looked fixedly (at something)" , "Gaped" , "Subjected to prolonged gaze" , "Gazed at in steady or prolonged way" , "Gazed intently at" .)
