The members of 5 Seconds of Summer apparently like getting naked. Less than two weeks after Calum Hood's naked video landed online, fellow member Luke Hemmings took to Twitter to share a glimpse at what he did with his bandmates during rehearsal.

On Monday, September 8, Hemmings uploaded a naked photo of Hood and Ashton Irwin on Twitter. In the snap, the two can be seen playing their instruments with no clothes on. "Rehearsal was getting boring," Hemmings captioned it.

Irwin recently also took to Twitter to share a clip of him and his bandmates hanging out backstage during iTunes Music Festival where they performed on September 4. In the clip, the boys can be seen showing off some dance moves with no pants on or shirtless.

In other news, 5 Seconds of Summer has announced an additional London show on their 2015 "Rock Out With Your Socks Out" tour. The band will make an appearance for the third show at Wembley Arena on June 14. Tickets for the newly-announced date go on sale on September 12.

"We are going to try to make the best live show possible for you guys, this is such a huge thing for us to be able to come and see you all," they said. "We cannot wait to play you the album and loads more. We love you guys and hope you are as excited as we are. Let's rock - let's rock today."

This is a very serious video. https://t.co/W2SaJRI9F2
