One term brought up to describe youngsters — famous ones (10)
I believe the answer is:
glitterati
But I can't explain it at all! Could you help me understand?
(Other definitions for glitterati that I've seen before include "Showbiz types" , "Glamorous, rich and famous people?" , "Fashionable people" , "Rich, beautiful and fashionable celebs" , "Celebrities" .)
