Twitter Gold: 5SOS get naked during rehearsal

When work is getting boring, most of us might have a chat with a co-worker, make a cup of coffee or have a quick look at Facebook. But for Aussie popstars 5 Seconds of Summer, that's apparently not enough. When band rehearsal got boring today (September 11), some of the group decided to strip down to nothing but their musical instruments. Take a look at band members Calum Hood and Ashton Irwin below. Naked pictures Calum Hood (pictured above, baring his bum) leaked online last month (August), but the popstar shrugged off it off — find out more about that happened here.
