And why does she have so much money to spend?
Because for some strange reason, people who can sing/act are valued the most in today's society...
With a few extra professions, such as footballers.

Yes, singing, kicking a ball and pretending to be somebody else = Worthwhile and deserving of vast amounts of money.

Police, firefighters, people in the medical profession, even scientists etc = Decent wage, but nothing in comparison.

Singers/actors/comedians etc even receive knighthoods from the queen.

A long way away from people who fought and survived wars, saved villages, rescued people in danger etc to earn their knighthoods.
