The Grown-Up Guide to Your New Favorite Boy Band, 5 Seconds of Summer

The band has mostly avoided courting gossip, but their biggest scandal to date would probably have to be Calum Hood's naughty leaked Snapchat. Back in August, a fan shared a very NSFW Snapchat of Calum showing off his member, which understandably caused quite a bit of chaos among the group's fans. However, instead of denying the validity of the video, Calum owned up to the Snapchat, saying that he is "still a teenage kid" and learning from his mistakes.
