It's nice to see president and disgraced royal in conversation (3,5)
I believe the answer is:
eye candy
'it's nice to see' is the definition.
I don't understand how the rest of the clue works.
(Other definitions for eye candy that I've seen before include "Vacuous Adonis" , "Gorgeous thing" , "Dumb blonde" , "Visually attractive thing" , "Beautiful people" .)
