Saintly, warm-hearted celebrity?
I believe the answer is:
'celebrity?' is the definition.
(I've seen this in another clue)
'saintly warm-hearted' is the wordplay.
'saintly' becomes 'st' (I can't explain this - if you can you should believe this answer much more).
'hearted' says to take the centre.
The middle of 'warm' is 'ar'.
'st'+'ar'='STAR'
Can you help me to learn more?
(Other definitions for star that I've seen before include "personality?" , "Twinkling celestial body" , "Five-pointed figure" , "Ball of fire" , "Actor in a principal role" .)
