The 'She Looks So Perfect' singers get naked in front of thousands of fans online.

5 Seconds Of Summer sent fans wild during a live radio interview with Max on Capital tonight (Sunday 23rd March), as the boys stripped down to their pants during the #AmericanApparelChallenge.

Luke, Michael, Calum and Ashton were challenged to answer a set of music-related questions correctly to win the game, however after failing to impress us with their Capital knowledge and numerous incorrect answers, the boys visit took a turn for the naked. Thousands of capitalfm.com viewers sent Twitter wild with a worldwide trend for #5SOSonCapital.

All praise @CapitalOfficial for that GREAT GAME that got @5SOS practically NAKED!
