The newly crowned Teen Heroes were nominated by Radio 1 listeners and chosen by a panel of celebrities including headliner Pixie, Oritse Williams from JLS, Radio 1 and 1Xtra DJs and experts from youth organisations. Radio 1 received over 700 nominations.

There's no crowd louder and more enthusiastic than the one at Wembley today, which made my headline performance all the more enjoyable. I loved it!"
