I doubt that article was targeting 'hip, young kids' who wouldn't get the reference though. Selena when used as a mononym as far as I've ever seen has never been used to reference Selena Gomez (they typically always use her last name) and has always been used to reference Selena Quintanilla. Selena Gomez own name may even be some parental homage to Quintanilla considering how old Gomez is. Even Banksy has been active since the 90s.
