Celebrities in high-speed transporter (8)
I believe the answer is:
starship
'high-speed transporter' is the definition.
'celebrities in' is the wordplay.
'celebrities' becomes 'stars' (I've seen this in other clues).
'in' becomes 'hip' (both can mean fashionable).
'stars'+'hip'='STARSHIP'
(Other definitions for starship that I've seen before include "The Enterprise in Star Trek is one" , "Sci-fi space vehicle" , "Enterprise, say" , "TV's USS Enterprise, for instance" , "Enterprise perhaps" .)
