I'm a little stuck... Click here to teach me more about this clue!

'reveal all?' is the definition.
'expose' can be an answer for 'reveal' (synonyms). I am not certain of the 'all?' bit.

'former model' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'model' becomes 'pose' (model can mean to pose).
'ex'+'pose'='EXPOSE'

'to' is the link.

Can you help me to learn more?

(Other definitions for expose that I've seen before include "Lay bare" , "Reveal or unmask" , "Make visible or apparent" , "hazard" , "Bring into view" .)

I've seen this clue in The Globe and Mail.
