With her current amount of money I think that would be a No. However, it is interesting since she directly makes what is she is getting paid for which is her music. There are obviously teams of people she employs to help with this process as well as the spin off products (merchandise, CDs, movies, etc.) but she directly makes what she sells like all musicians. If she was barely scraping by with just her music I think most people would say that she would be working class. So it gets blurry.

I think its similar to athletes who do the core work that they get paid to do (i.e. play the sport). But make additional funds by selling their name and likeness. So they could be considered working class but then you get to the amount of money they make as well.
