Rogue star upset body double (9)

I believe the answer is:

surrogate

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

'body double' is the definition.
'surrogate' can be an answer for 'double' (thesaurus). I'm unsure of the 'body' bit.

'rogue star upset' is the wordplay.
'upset' indicates anagramming the letters.
'rogue'+'star'='roguestar'
'roguestar' with letters rearranged gives 'SURROGATE'.

Can you help me to learn more?

(Other definitions for surrogate that I've seen before include "(A) substitute in office" , "stand-in" , "One standing in" , "Argues about rot with substitute or deputy" , "Deputising substitute" .)

I've seen this clue in The Guardian.
