The 21-year-old crept up the ranks of Nickelodeon, retracing the path of the Disney cannon fodder (Timberlake, Spears, Aguilera) a generation before her. Grande starred in two hit kids' TV shows until last year, when she released a debut album, Yours Truly. She could run up and down octaves like a kid on the stairs, earning her instant "mini-Mariah" comparisons. The music, too, was orthodox retro pop-soul. It was all grown-up and house-trained. Polarising crudely, it was everything the "bad" Miley Cyrus was not. Still aesthetically closer to Audrey Hepburn than a pole-dancer, Grande is, none the less, swiftly becoming a more versatile pop offering.
Already compared to fashion's biggest icon. When will your fave?
