Inexperienced reporter interrupted by that girl, an angelic being (6)
I believe the answer is:
cherub
'an angelic being' is the definition.
(I've seen this before)
'inexperienced reporter interrupted by that girl' is the wordplay.
'inexperienced reporter' becomes 'cub' (I've seen this in other clues).
'interrupted by' indicates putting letters inside.
'that girl' becomes 'her'.
'cub' placed around 'her' is 'CHERUB'.
(Other definitions for cherub that I've seen before include "Lovely child" , "Angelic child" , "little one with wings" , "Angel portrayed as a winged child" , "A heavenly winged babe" .)
