A singing brother by hotel, drowning in expenses in fancy area (7,5)

I believe the answer is:

beverly hills

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

'area' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for beverly hills that I've seen before include "star abode" , "City near LA, film stars' home" , "Expensive community" , "City in Los Angeles County, California" , "Upmarket area in Los Angeles" .)

I've seen this clue in The Guardian.
