Australian heartthrobs 5 Seconds of Summer recently sat down for a chat with Nova FM and were quizzed on several naked photographs of the members that have surfaced online over the past few months. 

The pictures, which can all be seen below, show the lads larking about without any clothes on and they admitted it's a regular occurrence because they like to have fun and be silly around each other.

Guitarist Michael Clifford first addressed the image in the centre, telling the radio presenter that "Calum (Hood) posted it on Facebook! I didn't know he was going to take a photo."

When asked who the naked guy in the kitchen is (far right), Luke Hemmings explained: "That's Calum, that's the guy that took the photo of Michael before. I came downstairs to have some breakfast in our London house and he was just naked in a beanie..."

Both stars then spoke about the picture of Calum, and Hemmings clarified the location: "That was in New Zealand... possibly Auckland?" He then laughed and admitted he was the one who shared it with the band's followers: "I posted that!"

Getting naked seems to be a popular thing among all-male bands as British hitmakers The Vamps recently confessed that stripping off in front of each other is something that happens a lot in their band too.
