re: The highest paid female DJ in the world

As someone who works in this industry, Paris Hilton's appeal is the same of other shell "artists" like Pauly D, they only sell tickets based on their celebrity status as guests just want to see them not an actual performance. Hakkasan is a 100 million dollar nightclub and they still give bookings to fringe Kardashians who've learned the basics in DJing (extremely easy obvi). Other figures like Deadmau5 and Above & Beyond are paid handsomely because they produce their own records and have helped bring an underground music scene into the mainstream.

TL;DR only brain-deads see Paris live
