Punk pop stars or not, 5 Seconds of Summer were still asked to follow the rules at a Los Angeles nightclub. WENN reports that the band were kicked out of The Nice Guy on April 4.

According to the site, the four singers were asked to leave the venue by security guards as they are all under 21. (Luke Hemmings is 18, Calum Hood is 19, Michael Clifford is 19 and Ashton Irwin is 20.)

WENN claims the band headed home after the incident.

It's been a busy year for 5 Seconds of Summer, who are reportedly in L.A. working on their second album. As excited as we are for new music, we're glad the band took a night off to head to the 2015 Kids' Choice Awards, where they rocked out in a slime-filled performance of "What I Like About You." The next night, they snagged an iHeartRadio Music Award for Best Fan Army.

Of course, 5 Seconds of Summer aren't all play. They recently signed Hey Violet to their label, Hi or Hey Records. In the announcement, Michael Clifford explained the situation by using the most perfect pop-culture metaphor ever: “We started Hi or Hey Records because we thought it would be cool as hell to have a label that was run by you guys. It’s like Catdog. We’re conjoined.”

“We’re looking for some punk rockers who have big dreams,” Ashton Irwin said, while Luke Hemmings added, “We went and saw them rehearse and stuff and they were playing songs for us and straight away we all knew.”
