5 Seconds of Summer fulfilled a LOT of 'Teenage Dreams' with their amazing Katy Perry cover.
Is there no song that 5 Seconds of Summer can't sing? Their super cover of Katy Perry's 'Teenage Dream' definitely fulfilled a few of yours - we saw you singing along on the screens!
The 5SOS boys really made the song their own - and the #5SOSFam lapped up every headband of Michael Clifford's bright green hair. Maybe he was inspired by Katy's own green do?
If you loved their performance at the #CapitalSTB, you can watch it again to your heart's content with our video above. You're welcome.
