5 Seconds of Summer have revealed that they often rehearse naked.

The pop-punkers surprised fans recently by uploading a photo of themselves practising in the buff.

Speaking to Young Hollywood, the Australians admitted that incidents like that are a regular occurrence.

Luke Hemmings said: "Stuff like that happens all the time. But sometimes you take a photo of it and upload it. I don't know how it doesn't get taken down."

Drummer Ashton Irwin added: "Do you want to know something funny? We uploaded a picture once of Michael recording naked in the booth. Our Facebook page got taken down. We had to plead with Facebook to put it back up. It was rough."

5 Seconds of Summer meanwhile are currently supporting One Direction on tour in North America, with their next date scheduled for Friday (September 19) in El Paso.
