An anonymous hand in front of the camera counted down the seconds before the song's introduction, revealing a timid-looking frontwoman Hayley Williams sitting on host Colbert's desk as it pulled away. The singer's nervousness was clearly just a put-on -- and a nod to the song's fake newsroom video -- as the singer belted out the bouncy tune with ease. Williams kept up the vulnerable, kooky act as she joined the band on an aptly rose-colored stage setup, twitching along to the irresistibly danceable track while flipping around her wet-look asymetrical hair. The song's 1980s inspiration was brought to life through the bright colors and outfits sported by the band members, with Williams rocking a Kermit-the-frog-green blazer bold blue eyeshadow.
