Most recent Hollywood trial? (6)
I believe the answer is:
latest
'most recent' is the definition.
('late' can be similar in meaning to 'recent')
'hollywood trial?' is the wordplay.
'hollywood' becomes 'la' (I've seen this in other clues).
'trial?' becomes 'test' ('test' can be a synonym of 'trial').
'la'+'test'='LATEST'
(Other definitions for latest that I've seen before include "Up-to-the-minute" , "Most recent (news)" , "News update" , "Most recent or tardiest" , "delayed more than all others" .)
