5 Seconds of Summer have admitted that there isn't much nude frolicking backstage on this year's One Direction tour.

The Australians supported the band on their Take Me Home jaunt in 2013 and they have been doing it all over again this year on the Where We Are run.

However, the lads told MTV that there is unfortunately less nudity this time round - especially from the One Direction camp.

Ashton Irwin said: "[There's] no naked Harry Styles, which is disappointing! It's a decrease of nudity on the tour this year."

The band meanwhile released their self-titled debut album in the US on Tuesday (July 22).
