Australian pop-punk heartthrobs 5 Seconds Of Summer recently did a photoshoot for Seventeen magazine and behind-the-scenes footage from the event has now been uploaded. 

In the video clip, which is just under three minutes in length, the lads open up about their favourite songs on their debut album and go on to talk about the most embarrassing things on their phones. 

Member Luke Hemmings explained: "The amount of just... if you went into my photos you'd find a lot of weird pictures of my band. Not like that! The photos of all the naked Calums... that's not the only one on there. The one with Calum's butt in the kitchen?"

Guitarist Michael Clifford went onto add that the most embarrassing thing people might discover on his cellphone are "texts from mum."

Earlier today, meanwhile, the lads shared exciting news with their followers on Twitter and told them that on November 5 they will appear live on 'The Ellen Show': "We're performing on @TheEllenShow next Wednesday!"
