One Direction has topped the list of Billboard's "21 Under 21," a ranking of the hottest young musical stars, based on music sales, concert ticket sales, social media influence and more. Justin Bieber, Miley Cyrus, and Ariana Grande also land in the top four. The annual Billboard "21 Under 21" ranking has been released and some of our favorite musical celebs make the list of the hottest young stars.
One Direction tops the list of "most powerful" music stars in the industry--because, of course, right?
Given their ability to churn out chart topping tunes, sell out concerts, fill theater seats for their movie This Is Us, and still have a big stadium tour ahead of them, they lead the pack by a mile.
Justin Bieber is still pulling his weight, however, coming in second place on the list, while Miley Cyrus' ability to up the shock value and keep her name on everyone's lips puts her firmly in third.
Newcomer Ariana Grande is showing she's a force to be reckoned with in fourth place with her number one debut album, "Yours Truly."
The ranking is determined by music sales, concert tours, social media influence and more.
Other notables include Lorde, Austin Mahone, Emblem3, Bridgit Mendler, and Fifth Harmony.
