'pop star well-off doling out cents old indian' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'coin' is the wordplay.
I cannot really see how this works, but
'coin' could be 'anna' (I have seen 'Old coin' mean 'anna' so perhaps 'coin' could also mean 'anna') and 'anna' is found within the answer.
This explanation may well be incorrect...
