Pragmatic type dealing with leading celebrities... (7)
I believe the answer is:
realist
'pragmatic type' is the definition.
(I've seen this before)
'dealing with leading celebrities' is the wordplay.
'dealing with' becomes 're' (regarding).
'leading' is a charade indicator (letters next to each other) (some letters go in front of others).
'celebrities' becomes 'alist' (A-list).
're'+'alist'='REALIST'
(Other definitions for realist that I've seen before include "Plato, for example" , "Non-dreamer?" , "One who sees things in a practical way" , "Someone who's pragmatic" , "Pragmatist" .)
