Fashion websites and blogs are talking about whether Lorde's now famous - or infamous, to some - black-tinted nails are the next big thing.
The 17-year-old caused a bit of a stir on social networking sites when she came out on stage with her fingertips painted black.
Some called it creepy; others felt it was an unorthodox kind of beauty.
Although many had not seen it before, it appears she may have been inspired by the work of some fashion houses, including that of designers Maki Aminaka and Marcus Wilmont.
