Listen to 5 Seconds of Summer Radio on iHeartRadio

The guys of 5 Seconds of Summer performed for an intimate group of fans at the iHeartRadio Theater in New York City this week. But before the band took the stage, they hung out with iHeartRadio's Paul The Web Guy where they received quite a few of their fans' tweet dares. It basically turned into a backstage game of "Tweet & Dare!"

The guys were great sports, and did everything from sing Spice Girls songs to rap battle about bananas! Check it out below:
