Idolator Hottest 30 Under 30: 18-13

We’re back with our roundup of the young, hot talent making their way through the pop world right now. In our week long look at the brightest pop stars — some of whom have barely made it through puberty — we’ve seen a new mom with a new stage name and Jay-Z‘s newest protege. Today brings us a British boy band, a Canadian songbird that adorably just slipped us her digits, and a polarizing siren we simply can’t get enough of. Check out our gallery to see which artists made the next round of our Hottest 30 Under 30 list.
