Earning massive success early on with their whole careers ahead of them, Billboard named the most powerful 21 artists under 21 recently.

This year's 21 Under 21 list found itself a victim of the British invasion, as boy band One Direction rocketed to the top of the chart, noting that they're the first UK group to have their first two albums debut at number 1 on the Billboard 200 chart.

Close behind is 19-year-old Justin Bieber, whose 45 million Twitter followers helped him achieve massive career success.
