Lady in bed: that's censored (6)
I believe the answer is:
banned
'censored' is the definition.
('ban' can be a synonym of 'censor')
'lady in bed' is the wordplay.
'lady' becomes 'ann' ().
'in' indicates putting letters inside.
'ann' inserted within 'bed' is 'BANNED'.
'that's' acts as a link.
(Other definitions for banned that I've seen before include "Taboo" , "Outlawed" , "expelled" , "Censored" , "Prohibited by censor" .)
