Forces out half of nude models (7)
I believe the answer is:
deposes
'forces out' is the definition.
('depose' can be a synonym of 'force out')
'half of nude models' is the wordplay.
'half of' indicates taking half.
'models' becomes 'poses' ('pose' can be a synonym of 'model').
'nude' with half the letters taken is 'de'.
'de'+'poses'='DEPOSES'
(Other definitions for deposes that I've seen before include "Removes from office" , "Gives testimony" .)
