Nothing in press about models? (6)
I believe the answer is:
posers
'models?' is the definition.
(I know this)
'nothing in press about' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'in' means one lot of letters goes inside another.
'about' indicates anagramming the letters.
'press' with letters rearranged gives 'psers'.
'o' inserted within 'psers' is 'POSERS'.
(Other definitions for posers that I've seen before include "Baffling questions" , "They pretend to be something they're not" , "Puzzling questions or problems" .)
