Perhaps Rivera or Versace's private numbers gathered by AI (6)

'perhaps rivera or versace's' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'private numbers gathered by ai' is the wordplay.
I cannot really understand how this works, but
'private' could be 'gi' (GI can informally mean a US soldier) and 'gi' is present in the answer.
'numbers' could be 'nn' (two N's - n can mean any number in maths) and 'nn' is present in the answer.
'ai' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
