Daily Mail reports, 5SOS rock Sweden after Luke Hemmings' ex-girlfriend Arzaylea Rodriguez slammed the front man on Instagram
The band belted their hit songs including She Looks So Perfect, Don't Stop and Good Girls.
Lead guitarist Michael Clifford opted for a relaxed jumper and jeans combo, paired with a baseball cap worn backwards.
Calum Hood, who plays bass, also went for an all-black look in skinny jeans and a black striped jacket and boots.
While drummer Ashton Irwin kept it cool and casual in a denims and a singlet.
Their show comes after Luke's ex girlfriend Arzaylea launched into an Instagram tirade, reigniting their feud following their breakup in May this year.
Last week, Luke posted a black and white photo of himself on Instagram with the caption: '2fast4u @ashtonirwin,' which led the young social media starlet to embark on an abusive tirade against him.
She fired back to the seemingly innocent photo with some very aggressive comments including: 'Yeah you always did finish fast.'
'Y'all need to realize none of these guys are perfect. I'm over being the one in trouble lmao,' she wrote.
H 'IM TIRED OF EVERYONE THINKING THIS IS FOR ATTENTION VECAUSE [sic] DEAD A-- IVE BEEN HOLDIN IN MY PAIN FOR A YEAR. I MADE A MISTAKE BUT HE MADE A MILLION,' Arzaylea added.
The two met at a party thrown by Kylie Jenner for her sister Kendall's 18th birthday in 2015.
The two kept their relationship relatively private for a number of months, before finally spilling the beans in October, when Arzaylea shared a photo of the pair kissing on Instagram.
