Actor spotted embracing husband (5)
I believe the answer is:
sheen
'actor' is the definition.
(I've seen this before)
'spotted embracing husband' is the wordplay.
'spotted' becomes 'seen' (spot can mean to see or notice).
'embracing' indicates putting letters inside.
'husband' becomes 'h' (abbreviation).
'seen' enclosing 'h' is 'SHEEN'.
(Other definitions for sheen that I've seen before include "Polish" , "Radiance" , "Surface shine" , "splendid clothing" , "Glow" .)
