5 Seconds of Summer performed in the iHeartRadio Theater Presented by P.C. Richard and Son Monday night and it was MONUMENTAL.
Fans waited outside all day to see the Aussie boys to perform, some even just to get a glimpse of them. The performance was electric and the intimate crowd was so loud it sounded like thousands of people were there, singing along with every word.
5SOS did their original songs including 'She Looks So Perfect' and 'Amnesia,' but also some epic covers of label-mate Katy Perry's 'Teenage Dream' and ended the show with the old-school jam 'What I Like You' by the Romantics.
Girls were brought to tears over the sight of the boys and dreams definitely came true for many.
Check out the the Keek videos that documented the incredible night that 5SOS took over Z100 and the iHeartRadio Theater from beginning to end!
