Intimate one knows celebrities (4-4)

I believe the answer is:

name-drop

(Other definitions for name-drop that I've seen before include "Refer to famous people in familiar way to impress" , "Casually mention famous people you know" , "Boast of acquaintance" , "Pardon me, being inclined to mention famous people I have met" , "Mention familiarity with famous people to impress" .)

I've seen this clue in The Guardian.
