Popular girl, a native originally of Mumbai? (6)

I believe the answer is:

indian

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

'mumbai?' is the definition.
I can't judge whether this defines the answer.

'popular girl a native originally' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'girl' becomes 'Di' (short for Diane or Diana).
'originally' suggests taking the first letters.
The initial letter of 'native' is 'n'.
'in'+'di'+'a'+'n'='INDIAN'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for indian that I've seen before include "May be Asiatic or N. American" , "IDA inn provided for this nationality" , "Delhi native perhaps" , "Type of club, file, tea or summer" , "Of a subcontinent in Asia" .)
